Alt-Regensberg Castle (Ruin) (Regensdorf)

The origins of Alt-Regensberg Castle date back to around 1040, when it was likely built by Lütold von Affoltern as the ancestral seat of the Lords of Regensberg. This noble family, whose exact origin is presumed to be in the Mâcon area, gained power and owned widely dispersed lands. Among other things, they were founders of the monasteries of Fahr and Rüti, as well as the towns of Regensberg and Glanzenberg. Around 1050, the Regensbergers took on ecclesiastical duties and built St. Niklaus Chapel in Oberregensdorf. Lütold I, son of the founder, subsequently named himself after the castle and fell in battle in 1088. In the early 13th century, Lütold IV expanded his power to such an extent that he was allowed to call himself Count of Regensberg and had the ancestral castle expanded with a stone curtain wall, a cistern, and economic buildings, with the tower being redesigned with carefully hewn bossed ashlar blocks.
