The Ismail Bey Complex The Ismail Bey Complex, situated in Kastamonu, was constructed between 1443-1461 AD by Kemalettin Ismail Bey, who was the ruler of the Candaroğulları Dynasty. An Arabic inscription found in the complex indicates that it was built in 1457. The complex is built on the Şehinşah rock, which has two rock tombs dating back to the 7th century BC. Located outside the city walls, the complex was built with the aim of developing settlement areas and providing a three-dimensional plan for the cultural center. The complex comprises an inverse planned public kitchen, a square planned tomb, an open courtyard, and a single Iwan. It also has a (U) shaped and single-floored theological school with a Sibyan School designed to serve both in winter (with a closed part) and in summer (with an open-air part). Additionally, an Inn with one entrance and no division and a single domed Turkish bath with a sıcaklık section along its width are also part of the complex. The Ismail Bey Complex stands as a remarkable example of the architectural excellence of the Candaroğulları Dynasty and its significance in Turkey's cultural heritage. The Ismail Bey Complex has undergone several repairs over different periods. However, the imaret, theological school, and tomb have mostly preserved their originality. The primary construction material used in the complex is yellowish kefeki stone, while rough stones were used as filler between walls. Some parts of the exterior surface were made of smooth stones, and a brick mixture was used for primary structures and inside the inns. The structures forming the complex are simple, with only expressive parts such as portals and domes having ornamentation. This simplistic approach gives the complex a dynamic feel as it is made up of basic elements. The Ismail Bey Complex serves as an essential example for analyzing location planning and material techniques. The complex reflects the highly organized foundations of settled life in Anatolia and shows that these types of structures existed throughout history, not just during the Early Ottoman Period. More importantly, it was built during a time when dynasties ruled rather than an empire.
