St. Oswald’s Chapel was the seedcorn of settlements in the region, the mother church of Hinterzarten and Breitnau and the oldest surviving parish church in the High Black Forest.

The chapel holds up to 250 people and is used for weddings, patron saint festivals and at Christmas (by the Hofgut Sternen). In addition, since 2012 during the summer months there is a fair here once a month around midday.
