St. Arbogast is the only church in Switzerland that is surrounded by a defensive wall. A church has existed here already in the 5th century. Mid 12th century the erection of a Romanesque church started, but it got never completed, due to the Basel earthquake of 18 October 1356, the most significant earthquake, historically documented in Central Europe.

Rebuilding started in 1359, from around the fortification of the church started and the wall around the church got built. It is 7 metres high! There are two gates and seen on the right an ossuary, built in 1513.
