The Staffelsee is a lake in the Garmisch-Partenkirchen district of Bavaria, Germany. The settlements of Murnau, Seehausen and Uffing lie on its shores. Within its 7 km2 (2.7 sq mi) area lie seven islands, the largest and only inhabited of which is Wörth. Wörth was the site of Staffelsee abbey, a Carolingian monastery founded in the 8th century and dissolved in the 11th century.
