Herrenberg Abbey Church

The Collegiate Church is the landmark of the city of Herrenberg and, due to its location on the Schlossberg slope on the Schönbuch, dominates the valley far and wide. Due to this location, it is jokingly called the "Brooding Hen of the Gäu" in reference to a hen watching over its chicks.
