Schwarzenberg Castle was based on a medieval fortification and together with St. George's Church dominates the scene of the large county town of Schwarzenberg.
The castle was probably founded in the 12th century as a fort and was the original base for the settlement of Schwarzenberg and its vicinity. The former castle was given its present appearance by a conversion into a hunting lodge for the Electorate of Saxony from 1555 to 1558. In 1851-52 its keep and south wing were raised and, in 1875-76, an office building extension was added.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.
