The Belogradchik Fortress, also known as Kaleto, is a historical monument located 1.5 km away from the town of Belogradchik, situated among the famous Belogradchik Mountains. It is one of the best-preserved strongholds in Bulgaria and it is a cultural monument of national importance.
The Romans built the Fortress during the 3rd century to guard the roads they’d built in the Balkan peninsula
The highest part of the Fortress, the Citadel, grants the perfect spot for surveillance as it was the main reason for the construction of the fortress. Upon the separation of the Roman Empire in 395, the Byzantines took control of the Fortress. Later, the newly formed Bulgarian state captured the area. Under the reign of Tsar Ivan Stratsimir, the fortress was enlarged and reinforced. During the Ottoman reign, the fortress underwent another reconstruction, and later a garrison was built.
