Rumeli Fortress was built by Fatih Sultan Mehmet II to control the ships passing through the Bosphorus, before the conquest of Istanbul. The fortress, whose construction started in March 1452, was completed in August of the same year. In historical sources, it is mentioned that 300 masters, 700-800 workers, 200 coachmen, boatmen and transporters worked in its construction. Hisar, lost its importance after the conquest and It has been used as a state prison since the 16th century. Buildings destroyed by the fire in 1746, were repaired in the time of Sultan Selim III. (1789-1807). Hisar, which has not attracted attention for many years, has seen a comprehensive restoration in 1953 during the 500th anniversary of the conquest.
