Uznaburg castle ruins, Medieval castle ruins in Uznach, Switzerland.
Uznaburg castle is a ruin on a hilltop near Uznach, with surviving wall segments and a square tower foundation still visible. The remains show how medieval fortifications were built in this region.
The castle was built around 1200 and was destroyed about 70 years later when a military invasion conquered the site. This event marked the end of local family rule over the location.
The ruins take their name from a family that ruled here during the Middle Ages, and visitors can still see wall fragments from that era. You can imagine how soldiers and servants once lived and worked within these spaces.
The ruin sits on the rocky Uznaberg at 491 m, about 60 m above the village and directly on the road from Uznach to Neuhaus. Only a few wall remains survive, including stretches of the ring wall, so the visit is short. The site was first investigated archaeologically in 1939.
The castle was reportedly taken in spring 1267 or 1268 after a months-long siege by Zurich troops under Rudolf of Habsburg. According to the account, the defenders threw live fish over the walls to show they had food, which made Rudolf suspect a secret access. A swineherd revealed it, and the castle was captured and destroyed.
