One of Albania’s best-preserved castles, Petrela Castle sits picturesquely on a steep slope overlooking a river, 15 km southeast of Tirana, along the road to Elbasan. On a clear day you can see all the way to Kruja. Emperor Justinian fortified this place to defend the settlement of Dyrrachium (now Durrës). The tower in the centre dates back to 500 AD; surrounding it are walls from the Byzantine period, laid out in a triangle, with round towers at the corners. The castle was used during Skanderbeg’s war against the Turks; his sister Mamica lived here and defended the castle, but it was eventually captured and used by Turkish soldiers.
