St. Paul's Chapter Church was built by Bishop Burchard (who also built the first Worms Cathedral) in 1002. It was originally a three-naved buttress basilica.
A Dominican monastery was added in 1226. Also in the 13th century, the stone dome-shaped tower roofs were added in the Byzantine style of Jerusalem's churches. These make the church a visible monument to the Crusades.
The Pauluskirche was desconsecrated and the monastery destroyed in 1797 in the interests of secularization. In the decades that followed, the church was used as a warehouse, a barn and finally as a municipal museum (1880).
In 1929, Dominican religious life began again here and is still an active community. The resident monks conduct services, prayers and confession, and some also work as hospital or prison chaplains. The Pauluskirche was badly damaged by bombing on February 21, 1945, but through the support of local citizens it was rebuilt and back in service in 1947.
The present nave of the Pauluskirche was rebuilt in the Baroque era, but the remainder of the building is 11th-century Romanesque.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.
