Alt-Regensberg Castle

Alt-Regensberg Castle is a ruined fortress on a moraine hill featuring a hexagonal layout with foundations measuring roughly 45 by 40 meters. The standing remains include a square tower with substantial walls and an elevated entrance that was originally accessible only by ladder.

The fortress was built in the mid-11th century and underwent several construction phases through the 15th century. A major turning point occurred in 1458 when merchant Rudolf Mötteli acquired the site and made interior alterations.

The name reflects its location on a glacial ridge and its role as a fortified settlement in the medieval landscape. Visitors today can observe the remaining walls and understand how the site once functioned as both a residence and a defensive position.

The slope is steep, and reaching the site requires secure footing and sturdy footwear. The ruin stands openly without railings, so care must be taken when walking across the aged stonework.

The stones from the crumbling structure were salvaged for local building projects, including the church of Regensdorf and bridges in Adlikon. This practice shows how medieval remains shaped the architectural heritage of the surrounding region.
