Stein Castle (Aargau)
Aargau
Stein Castle, located above the municipality of Baden in the canton of Aargau, Switzerland, is a medieval castle ruin of national significance. Built on a rocky promontory before 1000 AD, it served various noble families including the Lenzburgs, Kyburgs, and ultimately the Habsburgs. The castle functioned as an administrative center and housed the Habsburg archive, highlighting its historical importance. In 1415, Swiss Confederation forces besieged and destroyed the castle, which was later rebuilt as a fortress between 1657 and 1670. However, it was demolished again in 1712 following the Second Villmerger War, leaving only ruins today. Notably, the St. Nicholas chapel remains intact, offering visitors a glimpse into the castle's religious heritage. The site commands panoramic views over Baden’s old town and the surrounding valleys, making it a popular tourist attraction and public viewpoint. Restoration efforts in the late 20th century have preserved the ruins and made them accessible for exploration.
