Coat of arms
Petershausen Abbey (Kloster, Reichskloster, Reichsstift or Reichsabtei Petershausen) was a Benedictine imperial abbey at Petershausen, now a district of Konstanz in Baden-Württemberg, Germany.
It was founded as an exempt abbey named after Saint Peter in 983 by Bishop Gebhard of Constance, located on the northern shore of the Rhine river opposite to the episcopal residence at Constance with its cathedral. Gebhard dedicated the monastery church to Pope Gregory the Great and settled the abbey with monks descending from Einsiedeln.
Under Bishop Gebhard III of Zähringen and Abbot Theodoric (1086–1116), the Hirsau Reforms were introduced. In 1097 a filial monastery was established at Mehrerau near Bregenz. As Petershausen sided with the papacy in the Investiture Controversy, Gebhard III in 1103 was deposed at the instigation of Emperor Henry IV. The abbey was closed until 1106, the monks fled to the newly established Kastl Abbey in Bavaria. In 1159 the monastery burnt down, and was rebuilt and extended between 1162 and 1180.
