Jurisics Castle, named after Croatian nobleman Nikola Jurišić. The oldest part was built in the 13th century. The inner castle originally of Gothic style was extended later on. This building complex served as an estate castle and was also converted in the Renaissance and Baroque era. The character of the two islands still can be observed: it is visible that the fortress and the interior of the castle were surrounded by a moat.
During the Little War in Hungary, Pargalı İbrahim Pasha under the command of Suleiman the Magnificent laid siege to the castle in 1532. Jurišić and less than 1000 men defended the castle for 25 days without any artillery, despite 19 assaults.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.
