Ovech Fortress is a stone stronghold located east of the town of Provadia, 53 km west of Varna and 410 km east of Sofia.
The fortress is mentioned under different names in the historical chronicles. The oldest one is the Byzantine name Provat. Bulgarians referred to it as Ovech, while Turks called it Tash hisar (which translates from Turkish as stone fortress). Archaeological research established that the fortress was used in periods from the 3rd century to the first decades of the 7th century, and then from the 10th-11th centuries until the end of the 17th century.
