Schloss Buonas

Schloss Buonas is a medieval castle on a peninsula on Lake Zug in Switzerland, now operating as a training center. The complex features a rectangular courtyard, a recessed tower, and rests on limestone foundations directly at the water's edge.

The castle's first documented mention appears in a charter from January 1130, referencing the knights of Bochunna who controlled the area. The estate passed through various families over centuries before being acquired by Hoffmann-La Roche in 1997.

The castle shows features typical of medieval noble architecture as it developed in the Zug region. Visitors can observe how the structure combines building techniques from different periods, reflecting the craftsmanship valued locally.

The castle sits on a peninsula and is best reached on foot via local paths branching from the lakeshore. Visitors should plan ahead and respect private use restrictions, as access to the property may be limited.

From 1877 to 1979, a separate neo-Gothic villa called New Castle Buonas stood on the grounds alongside the original medieval structure. This second building was later demolished, but its design reflected the 19th-century love of medieval nostalgia.
