Ig Castle, also Sonnegg Castle or Zonek Castle, was first mentioned as hof Ig in 1369, when the noble house of Schnitzenbaum rebuilt an old estate building called Iški turn or Turnek as a defensive tower. In the late 15th century it was again rebuilt into a small manor and in 1510 sold to the house of Auersperg, which in 1581 sold it to the nobleman Johann Engelshauser. In 1717, Pope Clement XI authorized the opening of a private oratory at the castle. In 1805, the castle was inherited by a relative of the counts Engelshauser, Count Wilhelm Weikhard Auersperg.
The castle was the target of peasant revolts in 1515 and 1848, and was besieged by the Turks in 1528. During World War II, it served as an outpost for Italian carabinieri and Slovene Village Guard forces. In 1944, it was attacked and burned down by Partisans. After the war, it was repaired and converted into a women's prison. It is not currently open to the public.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.
