Kalaja e Ali Pashës

Kalaja e Ali Pashës [Ali Pasha’s Castle] was established when the Byzantines built a defensive tower up on the hill on the left bank of Viosa River. The site was successively developed during the Ottoman occupation, most notably by the capricious ruler Ali Pashë Tepelena in the early 19^th century. Until 1820, it was the second residence of the pasha.
