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 Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
