Rheinau Abbey (Kloster Rheinau) was a Benedictine monastery in Rheinau founded about 778 and suppressed in 1862. It is located on an island in the Rhine.
The foundation of the abbey, on a strategically sheltered bend of the Rhine, is supposed to have taken place in about 778. The abbey is first documented however in the 11th century. In 1114 a Romanesque basilica was dedicated here and in 1120 the still extant archive begun. The early history of the abbey, like that of many others, consists of an alternation between generous endowments and privileges from the Holy Roman Emperors, and oppression and fraud from the Vögte (lords protector). In 1126 Count Rudolf of Lenzburg founded the adjoining settlement of Rheinau.
Against the increasingly aggressive territorial claims of the Counts of Sulz the abbey made a treaty in 1455 with the Old Swiss Confederacy, which was intended to protect it against further attacks by the noble families of the Klettgau. In 1529 the Reformation swept in from Zürich and overwhelmed the abbey, which was abandoned shortly afterwards. It was re-established however in 1532, and became a centre of the Counter-reformation.
In the 18th century under Abbot Gerold II Zurlauben, Rheinau Abbey, like St. Gallen, enjoyed a late resurgence. Gerold had the abbey church (re-dedicated 1710) and the monastic complex (in construction up to 1744) magnificently re-built in the Baroque style, much as they appear today.
During the turmoil of the French Revolution and the French invasion of Switzerland in 1798, the abbey was temporarily suspended, but restored in 1803. The abbey's territory with the little town of Rheinau were added to the newly restored Canton of Zürich, which placed it under cantonal supervision in 1834 and from 1836 prevented it from accepting new novices. In 1862 the cantonal council decreed the dissolution of the abbey.
From 1603 until its dissolution the abbey was a member of the Swiss Congregation, now part of the Benedictine Confederation.
In 1867 in the abbey buildings a cantonal hospital and nursing home were set up. The later cantonal psychiatric clinic that developed here was closed in 2000. In the years 2003-2005 parts of the outbuildings were renovated. Today guided tours are available.
References:The Broch of Gurness is an Iron Age broch village. Settlement here began sometime between 500 and 200 BC. At the centre of the settlement is a stone tower or broch, which once probably reached a height of around 10 metres. Its interior is divided into sections by upright slabs. The tower features two skins of drystone walls, with stone-floored galleries in between. These are accessed by steps. Stone ledges suggest that there was once an upper storey with a timber floor. The roof would have been thatched, surrounded by a wall walk linked by stairs to the ground floor. The broch features two hearths and a subterranean stone cistern with steps leading down into it. It is thought to have some religious significance, relating to an Iron Age cult of the underground.
The remains of the central tower are up to 3.6 metres high, and the stone walls are up to 4.1 metres thick.
