Basilica of St. Castor

The church of Saint-Florin was built around 1100 and belonged to the canonical monastery of Saint-Florin. In the middle of the 14th century, the Romanesque apse of the church was replaced by a Gothic apse. In the years 1582 to 1614, the vaulting of the eastern nave followed. At the beginning of the 17th century, the bell towers were renovated. During the siege of Koblenz in 1688, during the War of the Palatinate Succession, the city was bombed by French troops. The church was badly damaged and had to be repaired between 1708 and 1711. After the secularization of the monastery in 1802, the church became the first church building in Koblenz to be consecrated as a Protestant church in the Rhineland.

The church of Our Lady was built from the 15th century on a site where churches have been built since the 5th century. During the War of the Palatinate Succession, Koblenz was bombed by French troops in 1688 and the tips of the Gothic towers burned down as a result. These were replaced in 1694 by the court architect of Kurtrie, Johann Christoph Sebastiani, with today's characteristic baroque tips. After its secularisation, the church of Our Lady was considered ruinous in 1803. Its roof was renovated in 1808 and a more extensive neo-Romanesque restoration was carried out from 1852 onwards. Badly damaged during the Second World War, the church was rebuilt between 1950 and 1955.

The Münstermaifeld synagogue was built in 1885-86. The Jewish community of Münstermaifeld already had a synagogue in the Middle Ages, mentioned in 1429. In 1816, a prayer room in a private house on Brunnengasse, which had been established after 1694, is mentioned. In 1885-86, the Jewish community built the new synagogue on a piece of land on Severusstrasse, which was renovated in the 1920s. During the pogrom of November 1938, the synagogue was devastated and burnt down.
