The castle was first mentioned in writing in 1265. The Freiherrenturm, built before 1200, is the oldest part of the castle. Its outer shells are made of mighty boulders. 1287 sold the last baron Rudolf III. for lack of descendants, the lordship of Wädenswil to the Johanniterhaus Bubikon. Wädenswil became a commander of the Johanniter. After the Reformation, the Johanniter sold the lordship of Wädenswil with all rights to the city of Zurich in 1549. In 1900 an initiative committee acquired the castle grounds and in 1902 established the Foundation for the Preservation of Alt-Wädenswil Castle.
