Fortified Church of St. Arbogast
The Fortified Church of St. Arbogast was founded in the 8th century, and since the 15th century, is completely enclosed by a circular wall. In the 14th and 15th centuries, the border region of Basel is indeed plagued with wars opposing the Habsburgs and the brand-new Swiss confederacy. The church of Muttenz has to potentially serve as a new refuge for the population in the event of future conflicts.
