Bollingen

History

Sandstone from Bollingen may have been used even in the Roman Empire era, but presumably is extracted and processed since 1000 AD. Among others it was used for the Grossmünster and Fraumünster churches in Zürich, as well as for the Einsiedeln and St. Gallen abbeys, or the Zunfthaus zur Meisen that was built in 1757 at the Münsterhof plaza in Zürich. In the European Middle Ages, the two settlements named and are mentioned as part of the later Herrschaft Rapperswil of the Counts of Rapperswil. The earliest document sealed at the Rapperswil Castle was related to the donation of the church of Unterbollingen to the Rüti Abbey, and also mentions among others a civitas of the town of Rapperswil as witnesses of Count Rudolf von Rapperswil in 1229. On the peninsula at Oberbollingen, a St. Nicholas Chapel is mentioned, where around 1229 a small Cistercian nunnery, later Premonstratensian convent associated with the Rüti Abbey was established by the Counts of Rapperswil; in 1267 it was united with the nearby Mariazell Wurmsbach Abbey. In 1519 a new church in honor of St. Pancras was inaugurated in Unterbollingen. After the Reformation in Zürich the church was acquired by the city of Rapperswil to be united with the , but since 1871 it is a parish church for its own.
