History
Between 1115 and 1118 the Augustinian monastery of Maria-Zell auf dem Schwarzwald was established by Count Bruno von Haigerloch-Wiesneck, Chancellor of Henry V and Provost of Straßburg, as competition to the Zähringen-founded Benedictine monastery of St. Peter auf dem Schwarzwald. The town and the monastery were dependent upon each other for many years. In 1716 a two-steepled Baroque monastery church was built, and the life of the community underwent a revival, until 1806 when the monastery was given up.
