History

After the original Benedictine abbey on the Altmünster Plateau was destroyed in 1542, the monks began building a new abbey or "Neumünster" in 1606 in the Grund. In 1618, a marble tomb was constructed to house the bones of John the Blind. The Abbey was destroyed in 1684 during the Siege of Luxembourg. The Abbey began to rebuild on the same site in 1688 and extended in 1720. The abbey is also now home to the Lucien Wercollier Cloister, where many works from the sculptor's private collection are permanently displayed. Since 1998, it has been the home of the European Institute of Cultural Routes. Bulgaria and Romania signed their Treaty of Accession to the European Union on 25 April 2005 at Neimënster.
