Bukelon Fortress, also known as Matochina Fortress, sits on a high plateau near the village of Matochina in southeastern Bulgaria, close to the Turkish border. Built during the late antique period, the fortress features a cross-shaped citadel with impressive defensive structures reaching 18 meters in height. The site witnessed pivotal historical events, including a major Roman defeat by Gothic forces in 378 AD and a crushing victory of Bulgarian Tsar Kaloyan over Latin Crusaders in 1205. Archaeological excavations reveal multiple layers of occupation spanning from the Early Iron Age through the Ottoman period, with stunning views across Bulgaria and Turkey.
