Al-Salam Mosque

Construction of the Church of the Holy Spirit in Wolfsburg began in 1961 and was finished in 1962. It was planned by the Finish star architect Alvar Aalto. The expressive, curved ceiling - a curved slab formwork made of Oregon pine - and the interior are designed from Aaltos own hand, down to the last detail.

Riddagshausen Abbey is a former Cistercian abbey founded in 1145, with the mother abbey of Cîteaux in Burgundy as a natural model. After a good sixty years of construction, the monastery church was consecrated in 1275. The guardhouse (which today houses the Cistercian museum) was already built at the end of the 12th century, while the small chapel for foreigners next door was completed shortly before the monastery church. A century after the dissolution of the congregation with the rise of Protestantism, a preaching seminary was founded in the monastery in 1690. With the secularisation of Riddagshausen Monastery in 1809 during the Napoleonic occupation, the preaching seminary was closed. From 1856 to 1883, the abbey church was renovated, and from 1962 to 1975 further improvements and repaints were carried out.

St. Catherine's Church was built in the early 13th century. In the second half of the 13th century, the church was transformed into a Gothic hall church as indicated by an indulgence of 1252. One of the towers burst into flames in 1815 after a thunderbolt. Between 1887 and 1890, the city construction officer Ludwig Winter restored the interior of the church. After the destruction of the church during the Second World War, restoration began in 1946. The helmets of the spire and the interior were renewed from 1957 to 1958.
