Wonnenstein Friary or Mary's Rose Garden Wonnenstein is a monastery of Sisters of the Third Order of Saint Francis in Teufen in the canton of Appenzell Ausserrhoden in Switzerland.

[1] In 1381 Kuno von Stoffeln, the Abbot of Saint Gallen, granted the land where the friary now stands to several nuns who lived in the area.

Because Wonnestein was located in the town of Teufen, which joined the protestant Ausserrhoden, ownership of the friary became a source of conflict.

In 1870 the federal government declared that the land within the walls of Wonnenstein and Grimmenstein would be part of Appenzell Innerrhoden and everything outside the walls would be Appenzell Ausserrhoden.

[1] Following the death in January 2020 of Gabriela Hug there were only two residents left at Wonnenstein.
