The Schwetzingen Park Mosque, also known as the Red Mosque is a decorative building in the park of Schwetzingen Palace in the former Electoral Palatinate, now the northern tip of Baden-Württemberg, Germany. Built in 1779–1793 AD, it is the oldest mosque-like building in Germany. The Schwetzingen Park Mosque was not intended as an actual place for Muslim prayer, and did not serve as one except for brief periods in the 1870s and 1980s.
