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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
