Rosenberg Castle, Hill castle ruin in Herisau, Switzerland
Rosenberg Castle is a ruined hill castle on the eastern crown of a small hill above Burghalden, north of Herisau. Its palas-like main tower measured 19 by 20 metres, with walls up to 3.2 metres thick at the base; a ground-level gate on the south side replaced an older entrance reached by climbing. Traces of storage and production buildings remain on the western crown.
The castle was built in the mid-12th century as a seat for the Rorschach family, who held power in the region. In the early 15th century it was destroyed by Appenzell citizens during their uprising against the Abbot's rule.
The castle's name and the family's identity came from the rose bush in the Rorschach coat of arms; Egolf von Rorschach took the name von Rosenberg after the castle was finished. The Rosenbergs stayed in the Abbot of St. Gall's service, and in 1271 Abbot Berchtold von Falkenstein celebrated Christmas here with 70 knights. The ruins, excavated in 1936/37, yielded weapons, iron tools and tiles.
The ruins sit on a hilltop and are reached on foot from Herisau on hiking paths. Wear sturdy shoes as you walk through the site, since there are no facilities or developed infrastructure at the location.
In 1271 the Abbot Berchtold von Falkenstein gathered about 70 knights here for a winter celebration, underscoring the castle's political importance. This gathering reveals how central the fortress was to regional power holders of that era.
