Uster Castle

The exact origins of the first fortification on the castle hill are not fully clarified, but a complex is presumed to have existed as early as 1000 or 1100. Around 1200, part of the property, including Uster Castle, passed to the Barons of Bonstetten. The oldest visible parts of the residential tower date from this period. In 1267, the Bonstettens received Uster as a fief from Count Rudolf of Habsburg. During the Appenzell War in the early 15th century, Schwyz troops occupied the complex, after which Johannes von Bonstetten concluded a Burgrecht treaty with Zurich in 1407. A fire destroyed the castle in 1492, and another fire struck the newly built wooden house in 1526. Subsequently, the tower was redesigned, and the complex was rebuilt in 1529 as a representative castle. After several changes of ownership and a period of decay, the castle was restored and expanded in 1752. In the 19th century, it temporarily served as the seat of the district administration before being acquired by Jakob Heusser-Staub in 1916, restored, and donated to the city of Uster as a foundation. It then housed the Cantonal Farmers' Wives' School and later a private school.

Uster Castle is located in Uster, in the Uster district of the Canton of Zurich, Switzerland, at an elevation of approximately 486 m above sea level.

Today, Uster Castle is privately owned. The complex is a testament to its eventful history, with the current buildings being the result of extensive renovations that have given the castle its present appearance.
