Bollingen is a village (Kirchdorf) within the municipality of Rapperswil-Jona in the Swiss canton of St. Gallen.
The village is located along the northern shore of the upper Lake Zürich (Obersee) between Jona and Schmerikon.
Sandstone from Bollingen may have been used even in the Roman Empire era, but presumably Bollinger Sandstein is extracted and processed since 1000 AD.
[3] 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.
Bollingen is known for the "Tower" built there by Carl Gustav Jung.
