Hereke Kalesi, Medieval fortress in Körfez, Turkey
Hereke Kalesi is a stone fortress positioned on a hilltop overlooking Izmit Bay in Kocaeli Province. The structure features multiple towers and thick defensive walls that define its medieval military character.
This fortress was built during the late Roman period when the region came under Byzantine control. In the 14th century it fell to Ottoman forces following a military siege.
The site takes its name from the village below, which has been home to people for centuries. Today locals gather here for events and celebrations that connect them to their heritage.
The site is easily accessible by car via main roads in the region. Visitors should expect uneven terrain and wear sturdy shoes when exploring the grounds.
Restoration work was guided by historical drawings from the 16th century that showed the fortress in its original state. These detailed illustrations proved invaluable in reconstructing the medieval design accurately.
