Biel Synagogue

The city church of Biel is a sacred building of the reformed congregation. It was first mentioned in 1228. The church was originally dedicated to St. Benedict of Nursia and belonged to the diocese of Lausanne until the Reformation in 1528. The present church was built between 1451 and 1470 in the late Gothic style by the master craftsman Wenzlin. The remains of the walls of the earlier Romanesque and Gothic buildings, which were partially demolished or bricked up during the construction of the church, have been preserved to the present day.

St. Mary's Church is the oldest of the three Roman Catholic parish churches in Biel. On the outside, the church adopts neo-Gothic forms; inside, it is one of the few Swiss churches in the expressionist style. The church building consists of an upper church, built by the architect Adolf Gaudy in 1927-1929, and a crypt, formed by the former church, built in 1867-1870 by the architect Wilhelm Keller.
