The tower, built around 1200 and inhabited by bailiffs from Zurich, was extended at the end of the 15th century to include a knight's house and farm buildings.

Around 1200, the Lords of Hegi built a residential tower, to which the Lords of Hohenlandenberg added the mighty knight's house with its corner towers around 1460. Little has changed in this impressive late Gothic appearance.
The castle has richly decorated interiors reminiscent of the period between the 15th and 18th centuries. The armory in the tower was once a place of politics. On the wall hang the coats of arms of the bailiffs of Zurich, who resided in Hegi from 1587 to 1805.
The castle has been owned by the city of Winterthur since 1947 and was also a youth hostel until 2000.
Since 2010, around 150 volunteers from the Hegi Castle Association have been running the site with a tavern, a Pro-Spezie-Rara plant garden, private and public events and museum tours with scenic interludes by the castle's own theater group. The castle tavern and museum are open at weekends from May to October.
