The Kastamonu Castle
This castle is one of the main symbols of Kastamonu, which is located in the highest point of the city. It was built by the Byzantine Komnenos Dynasty on the west side of the city on top of a central rock mass in the 12th century CE. Only the inner part of the original structure (the inner castle) has been preserved into the present day.
The castle is the best vantage point on Kastamonu, as it is 120 meters above the city, and easily accessible. Inside the castle, there are cisterns, dungeons, escape tunnels, and a tomb known as the “Bayraklı Sultan” (The Sultan with the flag).
