Brauweiler Abbey, a former Benedictine monastery, founded and endowed in 1024 by Pfalzgraf Ezzo, count palatine of Lotharingia of the Ezzonian dynasty and his wife Matilda of Germany, a daughter of Emperor Otto II and Theophano. Ezzo and Matilda were buried here, as were their two eldest sons Liudolf, Count Palatine of Lotharingia (d. 1031) and Otto II, Duke of Swabia (d. 1047).
From 1065 until his death in 1091, Wolfhelm of Brauweiler, later Saint Wolfhelm, was abbot here. His relics were enshrined in the abbey church, and miracles were reported at his tomb, but all traces of them were lost centuries ago.
The present abbey church, now the parish church of Saint Nicholas and Saint Medardus, is the third building on the site, built between 1136 and 1220 or later. The abbey was dissolved in the secularisation of 1803. The premises were subsequently used, under a Napoleonic law, as a hostel for beggars, and from 1815 under the Prussian regime as a workhouse.
From 1933 to 1945 the buildings were used for the internment, torture, and murder of political and social 'undesirables' by the Gestapo and the civil authorities of the Nazi government. Prisoners included Konrad Adenauer, the former mayor of Cologne and first Chancellor of the Federal Republic of Germany. From 1945 to 1949, it was an open camp for displaced persons administered first by the British Army and then by United Nations Relief and Rehabilitation Administration.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.
