Pernegg Abbey was founded as a Premonstratensian nunnery in 1153. It was founded by Ekbert and Ulrich, who also founded the Geras Abbey about 10 kilometres from Pernegg.
Pernegg became a community of canons in 1584. In 1700 it became an abbey but was dissolved in 1783 under the reforms of Emperor Joseph II. In the mid-19th century the premises were acquired by Geras Abbey. Since 1995 they have been used as a retreat and seminar centre for the monastery at Geras.
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.
