Kloster Rüti
Two important monastic foundations date back to the House of Regensberg: Around 1130 "Lütold II" and his wife "Judenta" and his son "Lütold III" founded the Fahr Abbey, a Benedictine nunnery that still exists, and with the foundation of Rüti Abbey in 1206 the family probably secured lands of the first extinction of the "Alt-Rapperswil" family around 1192; the Premonstratensian abbey was abolished during the Reformation in Zürich in 1525.
