Frauenthal Abbey occupies an island formed by the river Lorze, north of the hamlet of Hagendorn, near Cham, in the canton of Zug. Tradition dates its founding to 1231, but no founding charter survives; the abbey is considered Switzerland's oldest Cistercian community still at its founding site today. A first architectural record appears in a royal privilege of 1252.

In 1528, in the wake of Zurich's Reformation, most of the nuns left the abbey and the abbess handed it over to the Council of Zug. The community was restored in 1552 by Abbess Anna von Fulach. The Treaty of Jonen, signed on 21 February 1602, reorganised governance between the convent, Wettingen Abbey and the city of Zug. During the First War of Villmergen, in 1656, Zurich troops caused the abbey considerable damage, put at more than 4,000 guilders.

Between 1696 and 1698, a Vorarlberg master builder named Moosbrugger raised the abbey's south and east wings. The church was renovated in 1731 by Jost Bernhard Lips, who gave it a baroque interior, then remodelled again in 1775. A comprehensive restoration, carried out from 1972 to 1976, adapted the building to the liturgical reforms of the Second Vatican Council.

From 1953 to 1970 the abbey ran a school of home economics and agriculture for young women. In 1957 it founded a daughter house in Wisconsin, United States, Valley of Our Lady, raised to an independent priory in 1965. Since 2021, Frauenthal has changed its legal form to become a civil-law foundation, while remaining home to a community of Cistercian nuns affiliated with the Mehrerau Congregation.

Why this place is remarkable

Frauenthal is, by tradition, Switzerland's oldest Cistercian abbey still standing on its 1231 founding site — nearly eight centuries without relocation, through the 1528 Reformation, its 1552 restoration, the damage of the 1656 war, and a 2021 conversion to a civil foundation that did not empty it of its community.

History and origin

The traditional founding date of 1231 is supported by no surviving charter; the first architectural trace dates from a royal privilege of 1252. The abbey was emptied by the Reformation in 1528, restored in 1552, then reorganised by the 1602 Treaty of Jonen. The south and east wings were built between 1696 and 1698 by a Vorarlberg master builder, the church renovated in 1731 and again in 1775, before a comprehensive restoration in 1972-1976.

Before you go

The convent remains occupied by a community of Cistercian nuns: a place of religious life, to be visited with the discretion this implies.

The complex sits on the Lorze, whose hydraulic power once drove the mill's turbines; the weir of the Hagendorn power station survives on the river, alongside a road bridge and a wooden bridge.

Panorama of Bremgarten from the opposite bank of the Reuss, at the end of an autumn day: on the left, a covered wooden bridge with a long tiled roof crosses the river from a white gate tower; a foaming weir crosses the current along its full width; above the embankment wall, the town's houses line up in ochre, yellow and white facades, dominated by a tall clock tower with a red roof and two church spires. The river, smooth and dark, reflects the whole town in the lower half of the image.
