Schloss Buonas, Medieval castle on Lake Zug peninsula, Switzerland
The castle features a rectangular courtyard, a recessed tower, and stands on limestone foundations near the water's edge of Lake Zug.
The first documented mention of Schloss Buonas appears in a charter from January 1130, referencing the knights of Bochunna who controlled the region.
The castle maintains its status as a Class A Swiss cultural property, representing medieval noble architecture from the Canton of Zug.
The castle complex now functions as a training center for Hoffmann-La Roche pharmaceutical company, which acquired the property in 1997.
Between 1877 and 1979, the estate included two castles: the original medieval structure and a neo-Gothic villa called New Castle Buonas.
