This church was founded by Charlemagne’s grandson Louis the German in the 9th century, although most of the architecture is from between the 12th and 15th centuries.

Since 2016 it has been possible to view stonework from the 800s in the crypt after it had been sealed off for more than a hundred years.

As with the Grossmünster, Giacometti also contributed a stained glass window for this church, which you can track down in the north transept.
