Zwing Uri Castle

The slighting of Zwing Uri (Twing Üren) is mentioned in the White Book of Sarnen, a Swiss chronicle of 1470.

During the period of 1310 to 1320, the tower was still standing, and there are traces of a planned expansion into a full castle with a ring wall and a moat.

This expansion was interrupted at about six weeks into the construction work, and the castle was abandoned in ca.

The site remained unoccupied until 1868, when a restaurant was built, using stones from the ruin.

The remains were secured in 1928, when the ruin was acquired by the Schweizerischer Burgenverein.
