The convent is first mentioned in AD 1130 as
Vare (an old term used for "ferry"). The lands were donated by the
House of Regensberg. On 22 January 1130 Lütold II and his son Lütold III and his wife Judenta handed over lands and estates on the shore of the
Limmat around
Weiningen and
Unterengstringen-
Oberengstringen to the
Einsiedeln Abbey to establish a Benedictine convent. The Chapel of St. Nicholas already stood on the land. This may have been connected with the death of Lütold I in 1088 while engaged in battle against the forces of the Abbey of Einsiedeln. The convent was dedicated to
Our Lady. In addition to the medieval St. Nikolaus-Kapelle (
Saint Nicholas chapel), built around 10th century AD and now called
St. Anna-Kapelle, and the late medieval church of the convent, the parish church of Weiningen were subordinated to the convent. From the very beginning, the convent has been overseen by the
Abbot of Einsiedeln; the nuns are led in their daily life by a
prioress appointed by the abbot. The
bailiwick rights were first held by the Regensberg family, after 1306 by the citizens of the municipality of Zürich, and from 1434 to 1798 by the Meyer von Knonau family. Around 1530 the convent was suppressed during the
Reformation in Zürich, but it reopened in 1576. An era of prosperity during the 17th century led to a brisk program of construction: In 1678 the tavern
Zu den zwei Raben ("Two Ravens", the emblem of Einsiedeln Abbey) was built; from 1685 to 1696 the cloister and church tower were renovated; in 1703/04 a new
refectory was designed by Johann Moosbrugger; and a house for the chaplain was erected in 1730/34. From 1743 to 1746 the convent church was decorated with frescoes by the Torricelli brothers. In dissolving the old County (
Grafschaft) of Baden in 1803, the cantons of Zurich and Aargau established an exclave of Aargau within the canton of Zürich, for the former lands of the convent. Formerly part of the
Bishopric of Constance, the convent has been part of the
Roman Catholic Diocese of Basel since 1828. The canton of Aargau chose in 1841 to close all monasteries within its territory, but this was reversed in 1843 for convents. The negotiations between Einsiedeln Abbey and the cantonal authorities regarding assets and authority were completed nearly 90 years later, in 1932. At that point Aargau granted full autonomy to the conventual community. During World War II, from November 1943 to February 1944, 11 female Jewish refugees lived secretly in the cloister; unfortunately they had to leave for an unknown destination when the school was opened. On 1 February 1944, the convent established a
Bäuerinnenschule, i.e. an
agricultural school for women. On 1 January 2008 the convent was incorporated into the municipality of Würenlos, happening over a century after the municipality's initial attempts to absorb the 1.48-hectare area of the convent. On 22 January 2009 the former Abbot of Einsiedeln, Dom Martin Werlen, O.S.B., presented the nuns with a new community seal, thereby indicating that the nuns were in full control of the business affairs of their convent. In 2014 the women's agricultural school (
Bäuerinnenschule) had to close for financial reasons. == Cloister ==
