Rumeli Fortress, known in Turkish as Rumeli Hisarı, rises dramatically above the European shore of the Bosphorus in Istanbul. Sultan Mehmed II ordered its construction in 1452 as part of his preparations for the conquest of Constantinople, positioning it opposite Anadolu Hisarı at one of the narrowest and most strategically important points of the strait.
With three monumental towers, powerful defensive walls, a green museum courtyard and commanding Bosphorus views, the fortress is one of Istanbul’s most impressive examples of Ottoman military architecture. Today, visitors can explore the museum grounds, see historic artillery and discover the story of the stronghold that helped reshape world history.

Rumeli Fortress was commissioned by Sultan Mehmed II to control maritime traffic through the Bosphorus and prevent military supplies from reaching Byzantine Constantinople from the Black Sea. Construction began in March 1452 and was completed within the same year, an extraordinary achievement considering the fortress’s scale and steep hillside location.
The fortress was positioned directly opposite Anadolu Hisarı, which had been built on the Asian shore by Sultan Bayezid I. Together, the two fortifications gave the Ottomans far greater control over the narrow waterway. Rumeli Hisarı was also known historically as Boğazkesen, a name associated with cutting or controlling the strait.
Its three great towers were constructed under the supervision of leading Ottoman statesmen: Çandarlı Halil Paşa, Zağanos Paşa and Saruca Paşa. The towers are among the most imposing features of the fortress, with the Saruca Paşa Tower reaching approximately 28 meters in height.
After the conquest, the fortress gradually lost its original military importance and was later used as a state prison. It suffered damage from the 1509 earthquake and the fire of 1746, followed by repairs during the reign of Sultan Selim III. A major restoration began in 1953, and Rumeli Fortress opened as a museum in 1968.
Explore monumental Ottoman military architecture, museum collections, historic details and unforgettable Bosphorus scenery.
Rumeli Fortress is dominated by three enormous towers named after the Ottoman commanders responsible for their construction: Çandarlı Halil Paşa, Zağanos Paşa and Saruca Paşa.
Massive walls connect the main towers with smaller defensive towers and gates, following the natural contours of the steep Bosphorus hillside.
The museum garden displays Ottoman cannonballs, cannons from different periods, Byzantine stone works and a surviving piece associated with the chain once used to protect the Golden Horn.
Several viewpoints within the fortress grounds reveal the Bosphorus, the Asian shore and the Fatih Sultan Mehmet Bridge from a powerful historical setting.
The Zağanos Paşa Tower preserves an important Ottoman Turkish inscription, while the Saruca Paşa Tower contains surviving wooden levels and traces from the period when the fortress served as a prison.
Pine trees, redbuds and natural ground cover create a surprisingly green atmosphere within the massive stone enclosure, especially during spring.
