Church of St. Johann

The Münster was first built in 1064 as the Romanesque basilica of the Kloster Allerheiligen, then owned by the Benedictines. After centuries of economic and political decline, Michael Eggendorfer, the last abbot of the monastery, initiated the last renovations in 1521-22. During the Swiss Reformation, the abbey was abolished and the Münster became the second main church in the town in 1524.

The Motorway Chapel of Hegau (officially Emmauskapelle) is located in the service area of Hegau West near Engen on the Federal Highway 81 from Stuttgart to the south. Instead of the original, too expensive dome model by the Hungarian architect Imre Makovecz, the project by the Ravensburg architect Wolf R. Bürhaus was selected in an architectural competition. The complex consists of a high cross, an inner courtyard and a parallelepiped-shaped chapel. Access to the chapel is via a narrow inner passage.

The city church of Winterthur was built from the 13th to the 19th century. Apart from the tower, the oldest part that still exists today is the Romanesque-early-Gothic choir, which was built in the middle of the 13th century. It was built as an extension of the nave on the model of the Fraumünster in Zurich. Serious damage during the city fire of 1313 made its reconstruction necessary. From 1486 to 1490, a second tower was built on the south side of the choir. The nave was built between 1501 and 1518 and extended ten metres further west but was somewhat narrower than before.
