Former Amsoldingen Abbey Church, Romanesque church in Amsoldingen, Switzerland.

The former Amsoldingen Abbey Church is a transeptless pillar basilica with a raised choir and originally three apses; the present tower replaced the southern apse, whose foundations remain visible. The church was built before 1000 on the site of a structure from around 700 and shows Lombard influences. Its crypt, dating from around 1200, contains Roman spolia from Aventicum and Allmendingen.

The church replaced a predecessor built around 700 and was founded, by legend, by Rudolf II of Burgundy and Berta of Alamannia. A secular collegiate foundation was attached; it was devastated in 1191 during the Zähringen conquest of the Bernese Oberland and restored around 1200. The Gothic tower followed around 1400, the foundation was dissolved in 1484 and attached to Bern Minster, and the church became a parish church in 1501.

The church was dedicated to Saint Maurice until the Bernese Reformation of 1528. Shortly before it, the reformer Johannes Haller, an ally of Huldrych Zwingli, served as pastor here but had to leave Amsoldingen in 1525 because of his marriage. From 1726 to 1738 Samuel Lutz, a friend of Nikolaus Ludwig von Zinzendorf, lived here and made the village a centre of Pietism.

The building sits on Chorherrengasse 4 and welcomes visitors interested in exploring its spaces. Regular community activities mean opening times may vary, so checking ahead is helpful for planning a visit.

The crypt, built around 1200, holds Roman spolia from Aventicum and Allmendingen walled into it. Until 1876 it served as the parish house cellar and a cheese store. The tower replaced the southern apse, whose foundations are still partly visible.
