Explore the Justinian Bridge

Bridge of Justinian – An Imperial Crossing at the Edge of Adapazarı

The Bridge of Justinian, also known as the Sangarius Bridge, Justinianus Bridge and locally as Beşköprü, is one of the most impressive surviving monuments of the Early Byzantine period in Anatolia. It stands in the Serdivan district of Sakarya, around 5 kilometres southwest of central Adapazarı.

The monumental limestone bridge was commissioned by Emperor Justinian I, who ruled the Eastern Roman Empire from 527 to 565. Construction began in the late 550s and the bridge was completed by AD 562, creating a permanent stone crossing on one of the empire's most important roads between Constantinople and the eastern provinces.

The bridge measures approximately 365 metres including its abutments, is about 9.85 metres wide and has 12 arches. Seven great central arches form the monumental core, while five smaller openings helped manage floodwater at the approaches.

Following a long restoration and archaeological program, the historic Sangarios Bridge was officially reopened in 2026. Today visitors can once again walk through a landscape that combines Roman engineering, Early Byzantine imperial ambition, archaeological remains and one of Sakarya's most important historic landmarks.

One of Justinian's Great Public Works

Why Is the Bridge of Justinian Important?

The bridge combines imperial strategy, monumental architecture and sophisticated Roman engineering.

The Bridge of Justinian was not built as an isolated local crossing. It formed part of the great transportation network that connected Constantinople with the Roman Empire's eastern territories. This route had military, administrative and commercial importance, especially at a time when the eastern frontier faced the powerful Sasanian Empire.

Before the stone bridge was constructed, ancient sources describe a less reliable timber or pontoon crossing that could be damaged or swept away during floods. Justinian's solution was characteristically ambitious: replace a vulnerable crossing with a massive permanent structure capable of carrying the imperial road across the floodplain.

The bridge is also important because so much of its original form survives. Its long masonry deck, great central arches, unusual pier shapes, supplementary hydraulic structures and archaeological remains preserve evidence of the technical knowledge available to late Roman engineers.

For travelers following our guide to places to visit in Sakarya, the Justinian Bridge is one of the province's most important historic sites and an excellent cultural counterpart to Sapanca Lake, Taraklı and Acarlar Floodplain Forest.

The Emperor Behind the Monument

Emperor Justinian I and His Building Program

Justinian I ruled the Eastern Roman Empire from AD 527 to 565. His reign was marked by military campaigns, legal reform and an extraordinary program of monumental construction.

The same emperor responsible for rebuilding Hagia Sophia in Constantinople also invested heavily in fortifications, churches, roads, aqueducts and bridges across the empire. These projects were not merely decorative: they supported military movement, administration, trade and the projection of imperial authority.

The Sangarius crossing fitted directly into that strategy. A reliable bridge west of the Anatolian interior improved communication between the capital and the eastern provinces, turning a difficult river crossing into a permanent piece of imperial infrastructure.

527–565

The reign of Emperor Justinian I, one of the most important rulers of the Eastern Roman Empire.

Imperial Roads

Roads and bridges helped troops, officials, messengers and goods move across the empire.

Hagia Sophia Era

The bridge belongs to the same remarkable age of imperial construction as Justinian's Hagia Sophia.

Eastern Strategy

The crossing strengthened links between Constantinople and territories facing the empire's eastern frontier.

Public Engineering

Justinian's building program combined architecture, logistics, military planning and civic infrastructure.

Monumental Message

The bridge demonstrated both practical engineering skill and the power of the imperial state.

Procopius, Agathias and Paul the Silentiary

When Was the Bridge of Justinian Built?

Modern sources sometimes give slightly different construction dates, usually ranging from AD 558 to 562. This is not unusual for a monument known through several ancient texts written at different stages of the work.

The historian Procopius, who recorded Justinian's building projects, described the bridge while construction was still in progress. Other writers, including Agathias and Paul the Silentiary, celebrated the completed monument. The surviving literary evidence places completion in AD 562.

For visitors, the simplest way to understand the chronology is that the bridge was built during the final years of Justinian's reign, with construction underway around 558–560 and the monumental crossing completed by 562.

Limestone Masonry on a Monumental Scale

Architecture of the Justinian Bridge

The bridge is built predominantly from large blocks of limestone masonry. Its scale is immediately striking: the structure stretches for roughly 365 metres including the abutments and carries a roadway almost 10 metres wide.

At its center are seven large arches, each spanning roughly 23 metres. These are supplemented by five smaller arches positioned toward the approaches, creating a total of 12 openings. The smaller arches helped relieve water pressure during floods.

The bridge's piers are especially interesting. Their substantial projecting buttresses were shaped to interact with moving water and to reduce destructive pressure against the masonry. UNESCO documentation highlights the unusual combination of rounded and pointed forms as one of the structure's distinctive engineering features.

365 m

Approximate length including the abutments in the official heritage description.

9.85 m Wide

An unusually broad deck for a surviving bridge of this period.

7 Main Arches

The monumental central arches form the visual and structural heart of the bridge.

5 Smaller Arches

Subsidiary openings helped accommodate overflow near the bridge approaches.

Limestone

Large limestone blocks create the bridge's heavy, durable masonry construction.

Massive Piers

Strong pier buttresses were designed to manage hydraulic pressure and protect the arches.

Look closely: the most interesting engineering details are not only the arches. Study the shapes of the piers, the masonry joints, the smaller overflow openings and the relationship between the bridge and the surrounding floodplain.
Seven Great Spans and Five Smaller Openings

The 12 Arches of the Sangarius Bridge

The bridge's twelve openings were not designed as twelve identical arches. Instead, the engineers created a hierarchy of spans that responded to the main water channel and the wider floodplain.

The seven great central arches are the most visually impressive. Their broad semicircular openings allowed the main body of water to pass between heavy stone piers. Toward the ends, the bridge transitions into smaller subsidiary arches.

This combination reduced the risk of floodwater becoming trapped behind a solid embankment. It also allowed the long approach structure to remain integrated with the river landscape.

Central Sequence

Seven broad arches create the monumental central crossing.

Approximately 23 m

The main arch spans are roughly 23 metres each according to UNESCO documentation.

Overflow Openings

Five smaller arches provided extra capacity when floodwater spread beyond the main channel.

Heavy Stone Piers

The arches rise from substantial masonry supports designed for a powerful river environment.

Long Horizontal Profile

The repeated openings give the bridge its extraordinary visual rhythm across the floodplain.

Best View

Step away from the deck where permitted to appreciate the sequence of arches as a complete structure.

Why Is the Sakarya River No Longer Under the Bridge?

The Sangarius River and the Changing Landscape

One of the first things visitors notice is the apparent mismatch between the enormous bridge and the much smaller watercourse visible today. The bridge was constructed for the ancient Sangarius — the Sakarya River, yet the modern main river channel now lies several kilometres to the east.

Today the bridge crosses the smaller Çark Deresi, known in Antiquity as the Melas. This stream drains water from nearby Sapanca Lake toward the Sakarya basin.

Historical and geomorphological evidence indicates that the main river shifted eastward during the Middle Ages, probably reaching something close to its modern course by the 13th century. The bridge therefore survived even after the landscape around it changed dramatically.

Ancient Sangarius

The bridge originally carried the imperial road across the river known today as the Sakarya.

Modern Çark Deresi

Only the smaller stream connected with Sapanca Lake now passes through part of the bridge system.

River Shift

The main Sakarya River gradually changed course and now flows several kilometres farther east.

Floodplain Engineering

The bridge's long form and smaller relief arches reflect the broad hydrological landscape it once crossed.

Medieval Change

The major river-course shift is generally associated with the medieval period, probably by the 13th century.

A Landscape Archive

The bridge preserves evidence not only of history but also of long-term environmental change.

More Than a Bridge

The Triumphal Entrance, Apsed Building and Supplementary Structures

The Justinian Bridge was conceived as a monumental architectural complex, not simply a line of arches across a river. Ancient and early modern descriptions record additional structures at both ends of the crossing.

At the western side there was once a monumental entrance or triumphal arch. Although the complete arch no longer survives, historic drawings and archaeological remains help reconstruct the ceremonial character of the bridge approach.

At the eastern end are the remains of a large apsed structure. Its original function is uncertain. Because of its form and orientation, it has sometimes been interpreted as a ceremonial or religious feature, but no single explanation is universally accepted.

The bridge also had supplementary vaulted masonry and hydraulic structures that helped manage the flow of water around the crossing. Recent restoration and excavation have made the wider archaeological setting far easier to understand.

Western Entrance

Remains survive from the monumental gateway that once emphasized the approach to the bridge.

Apsed Structure

A large apsed monument at the eastern side remains one of the site's architectural mysteries.

Vaulted Remains

Additional masonry structures reveal that the crossing was more complex than the bridge deck alone.

Breakwaters

Supplementary hydraulic elements helped protect the bridge from strong and changing currents.

Historic Drawings

19th-century documentation preserves evidence for architectural elements that no longer stand intact.

Archaeological Context

The surrounding remains help explain the bridge as part of a larger transport and service landscape.

Sangarius, Pontogephyra and Beşköprü

Why Is the Justinian Bridge Called Beşköprü?

The modern Turkish name Beşköprü literally means "Five Bridges," but this is misleading: the monument does not have five bridges and does not have only five arches.

The name appears to have developed through a long linguistic transformation. The bridge was once referred to simply with the Latin word pons, meaning "bridge." Later Greek-speaking communities treated the word as if it were a proper name and used forms such as Pontogephyra, effectively meaning "Pons Bridge."

Over time the name changed further into forms resembling Pentegephyra, which could be understood as "Five Bridges." The Turkish form Beşköprü continued that later interpretation.

Do not let the name confuse you: the surviving Justinian Bridge has 12 arches. "Beşköprü" is a historical place-name, not a description of its actual arch count.
Türkiye's World Heritage Tentative List

The Bridge of Justinian and UNESCO

The Bridge of Justinian was submitted to the UNESCO World Heritage Tentative List in 2018 under cultural criteria (iii) and (iv). The nomination highlights the bridge's historic, technological and architectural importance.

UNESCO documentation emphasizes its exceptional survival, its relationship with Justinian's imperial transportation network and the distinctive engineering of its pier buttresses. It also identifies the bridge as an outstanding example of late Roman architectural and technical knowledge.

A place on the Tentative List does not mean that the bridge is already inscribed on the World Heritage List. Rather, it identifies the site as a property Türkiye may consider for future nomination.

2018

Türkiye submitted the Bridge of Justinian to the UNESCO World Heritage Tentative List.

Criterion (iii)

The nomination recognizes the bridge as exceptional testimony to Justinian's imperial transport and military system.

Criterion (iv)

The structure is presented as an outstanding example of late Roman engineering and public works.

Serdivan, Sakarya

The UNESCO property is identified within Sakarya Province's Serdivan district.

Tentative, Not Inscribed

The site is a candidate on Türkiye's Tentative List rather than a fully inscribed World Heritage Site.

Exceptional Integrity

Its surviving masonry, arches and associated remains preserve much of the monument's original form.

Restoration, Excavation and Reopening

The 2018–2026 Restoration of the Justinian Bridge

A major conservation and archaeological program began around 2018. The project addressed the bridge's stone fabric, arches, piers, associated structures and the archaeological landscape around the monument.

During the works, archaeologists documented a range of finds and structures in the surrounding area. Reported discoveries included bronze coins, marble architectural fragments, inscriptions, small bronze objects and remains associated with baths, a cistern and vaulted buildings.

The restoration also improved the presentation of the site, with conservation of original stonework, strengthening where required, landscape organization, visitor circulation and architectural lighting.

The restored historic Sangarios Bridge was formally opened on 31 July 2026, bringing the monument back into active cultural and visitor use after years of restoration.

2018

The long restoration and excavation phase began around the same period as the UNESCO Tentative List submission.

Archaeological Excavation

Work around the bridge revealed architectural remains and portable finds from the surrounding historic complex.

Stone Conservation

The bridge's piers, arches and masonry were repaired with emphasis on preserving original character.

Historic Landscape

Associated remains such as the entrance area, bath, cistern and other structures were incorporated into visitor interpretation.

Lighting

New lighting was introduced to improve presentation while respecting the historic identity of the monument.

31 July 2026

The restored Sangarios Bridge was officially reopened to visitors.

Current status: the bridge is no longer in the long restoration closure described by many older travel pages. It reopened in 2026, although temporary access arrangements can still change for conservation, events or site management.
A Wider Complex Around the Crossing

Archaeological Discoveries Around the Bridge

The recent excavations have strengthened the idea that this was more than a stand-alone river crossing. The landscape around the bridge supported infrastructure connected with travel, logistics and activity along the imperial route.

Among the reported architectural discoveries are remains of a bath complex, a cistern that supplied water, vaulted structures and additional spaces around the bridge approaches.

Portable finds recovered during the wider project include bronze coins, a marble capital decorated with a cross, marble columns and fragments, inscription pieces and small bronze objects. Together they help archaeologists reconstruct how the area functioned over time.

Bath Complex

Excavated remains indicate services and activity around the strategic crossing.

Cistern

A water-storage structure reflects the infrastructure required around a busy transport corridor.

Marble Elements

Columns, fragments and a cross-decorated capital add to the architectural evidence from the site.

Bronze Coins

Coins recovered during excavation contribute chronological evidence for activity around the bridge.

Inscription Fragments

Marble inscription pieces are among the discoveries documented during the restoration period.

Ongoing Interpretation

New archaeological evidence continues to refine how historians understand the wider bridge complex.

The Best Details to Look For

What to See at the Bridge of Justinian

The monument is best appreciated slowly. Rather than simply crossing from one side to the other, look at how the bridge's architecture changes along its length and how the archaeological remains relate to the approaches.

The Seven Main Arches

Stand back where possible to appreciate the monumental scale and rhythm of the central spans.

The Smaller Arches

Notice how subsidiary openings extend the bridge across the broader floodplain.

Pier Buttresses

Study the unusual rounded and pointed water-management forms projecting from the bridge piers.

Western Gateway Remains

Look for the surviving evidence of the monumental entrance that once marked the bridge approach.

The Apsed Structure

Examine the remains at the eastern side and consider the still-debated original function.

Restored Stonework

Compare original masonry surfaces with carefully conserved and stabilized areas.

Archaeological Zone

The surrounding remains help explain the crossing as a larger transport and service complex.

Çark Deresi

Observe the small modern watercourse and imagine the much greater ancient Sangarius River landscape.

Best way to experience the site: first view the bridge from the side for its full scale, then walk the deck slowly, stopping to examine the pier shapes, arch sequence and archaeological remains at both ends.

Light, Weather and Comfortable Walking

Best Time to Visit the Bridge of Justinian

The bridge can be visited throughout the year, but weather and light strongly affect the experience. Because much of the site is exposed, spring and autumn are especially comfortable.

Spring

Mild temperatures and green surroundings make this one of the most pleasant seasons for walking and photography.

Summer

Visit in the morning or later afternoon to avoid the strongest midday heat and glare.

Autumn

Comfortable temperatures and softer light work well for long side views of the limestone structure.

Winter

The bridge remains atmospheric in cooler weather, but exposed stone surfaces can be wet and slippery.

Morning

Often best for quieter conditions and comfortable walking, especially in warm months.

Late Afternoon

Lower-angle light can reveal texture in the arches, piers and limestone masonry.

How Long to Spend

How Much Time Do You Need at the Justinian Bridge?

30–45 Minutes

Enough for a quick walk, several photographs and a basic look at the arches and bridge deck.

45–60 Minutes

A comfortable first visit with time to examine the pier forms and archaeological remains.

60–90 Minutes

Best for history lovers, careful photography and reading the site as a complete archaeological complex.

2 Hours

Allow this if you enjoy architectural detail, slow photography or detailed historical interpretation.

Half Day

Combine the bridge with central Sakarya, local museums, food and another nearby cultural stop.

Full Day

Pair the Justinian Bridge with Sapanca Lake, Taraklı or another wider Sakarya destination.

Arches, Limestone Texture and Monumental Perspective

Photography at the Bridge of Justinian

The bridge is one of Sakarya's strongest architectural photography locations. Its long horizontal profile, repeating arches, massive piers and pale limestone create very different compositions depending on where you stand.

Full Side Profile

Move far enough away to show the bridge's extraordinary length and repeating arch rhythm.

Low-Angle Arches

Use perspective to emphasize the scale of the main central openings.

Pier Details

Photograph the rounded and angular buttress forms that distinguish the bridge's engineering.

Stone Texture

Side light reveals weathering, tooling and joints in the limestone masonry.

Leading Lines

The long bridge deck creates powerful perspective lines toward the opposite approach.

Respect Archaeology

Do not climb on fragile remains or cross barriers simply to obtain a photograph.

Photography tip: a wider lens is useful on the bridge deck, while a moderate telephoto lens can compress the repeating arches and emphasize the monumental scale from a distance.
A Historic Stone Monument

Accessibility at the Justinian Bridge

The bridge is far easier to approach than a remote archaeological site, but visitors should remember that it is a 1,500-year-old stone monument with archaeological areas around it.

Restoration has improved visitor circulation, yet exact accessibility can vary between the bridge deck, approach areas and excavated remains. People with limited mobility should check current surface and access arrangements before a dedicated visit.

Urban Access

The bridge lies close to Adapazarı and Serdivan rather than in an isolated rural location.

Stone Surfaces

Historic paving can be uneven and requires more care than a modern sidewalk.

Wheelchair Planning

Confirm the current accessible route between parking, the bridge deck and interpretive areas.

Strollers

Possible in many areas, though uneven historic surfaces can make movement slower.

After Rain

Stone paving can become slippery in wet weather; choose footwear with good grip.

Archaeological Areas

Excavated remains may not provide the same level of step-free access as the principal visitor route.

Just Southwest of Central Adapazarı

How to Get to the Bridge of Justinian

The Justinian Bridge stands in the Beşköprü area of Serdivan, approximately 5 kilometres southwest of central Adapazarı. Its urban-edge location makes it one of Sakarya's easiest major historic monuments to add to a day itinerary.

From Adapazarı

The bridge is only a short drive from the city center, depending on traffic and your starting point.

From Serdivan

Local roads provide direct access toward the Beşköprü / Maltepe area surrounding the monument.

From Sapanca

The bridge can be combined easily with Sapanca Lake on a broader Sakarya sightseeing route.

From Istanbul

A day trip is possible by private vehicle, especially when paired with Sapanca or another nearby stop.

Private Vehicle

The most flexible option if you plan to combine several Sakarya attractions in one day.

Taxi / Local Transport

Because the bridge is close to the urban area, taxi access is generally more practical than at remote archaeological sites.

Navigation tip: search for Justinianus Köprüsü, Sangarios Köprüsü or Beşköprü Sakarya. These names all refer to the same historic monument.
