Iberg Castle, St. Gallen

Iberg Castle is a medieval ruin consisting of a main building and gatehouse situated at about 740 meters (2,430 feet) in elevation, built with carefully cut stone. The structures fit closely into the mountain landscape and show the typical defensive design of castles from that era.

The castle was built around 1200 and was later destroyed by fire, which led to loss of its original structure. Rebuilding attempts remained unfinished and the site remained in ruins afterward.

The ruins show building methods that were common in the medieval region and remain visible today through the stonework and layout. It stands as evidence of how local castles protected and watched over their surroundings.

You can find the castle ruins on Am Iberg street in Wattwil, easily located using coordinates 47.2975°N and 9.08°E. The site is accessible on foot, though paths are limited and can become slippery depending on weather conditions.

The castle is surrounded by a defensive ditch that was specifically designed to protect against attacks from the south and is still visible today. This ditch shows how the castle builders used the landscape to strengthen their defense line.
