Gutnau Priory, also spelled Guttnau or Guttenau (German: Kloster Gutnau, Guttnau or Guttenau), was a small Benedictine nunnery in Neuenburg am Rhein, in the district Breisgau-Hochschwarzwald in Baden-Württemberg in southern Germany.
According to Caspar Molitor, abbot of St. Blaise's Abbey,[1] the nunnery was founded in 1181 by Guta, sister and heiress of the last lord of Au (Auggen, Owon), on and with her inheritance; Guta was a nun of Sitzenkirch Priory, which was subordinate to St. Blaise's.
The nunnery buildings were apparently first sited right on the bank of the river Rhine, but were later relocated further inland for fear of flooding.
By 1492 the monastery was no longer able to finance itself and became a subordinate provostry of St. Blaise's Abbey.
In 1525 the nunnery was plundered and laid waste in the Peasants' War,[2][3] although according to Caspar Molitor a community of some sort was resident in 1530.
