Drisht Castle is a ruined castle above the modern Albanian village of Drisht, medieval Drivastum. The earliest traces of fortifications date to the late Neolithic era. In the 9th century, it was part of the defences of the Zeta principality.
Part of castle was built in the 13th century during the Byzantine rule. The current walls and towers date to 1396–1478 during the Venetian era. In the 14th century the castle became independent of Shkodra. In 1442 the castle was taken from Serbian Despot Đurađ Brankovićby the Venetian forces. It finally fell to the Ottomans during the massive siege of Shkodra in 1478.
There are the remains of 11 houses inside the castle walls.References:
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
