The abbey in Tegernsee is a former Benedictine monastery that is located directly on Lake Tegernsee. The abbey, like the town that grew out of it, is named after the lake, whose name can be translated from the Old German, tegarin seo, meaning large lake. Founded in the 8th century, the abbey represented one of the most important Benedictine communities in Bavaria until 1803. Today, however, the former monastery building is known as Tegernsee Castle and is owned by the Wittelsbach family. The former monastery church became the local parish church of St. Quirinus. Today, the large grounds also house the well-known Herzoglich Bayerisches Brauhaus Tegernsee brewery, restaurant, brew pub and Tegernsee Gymnasium.
