Torpa stenhus, Medieval castle in Tranemo Municipality, Sweden

Torpa stenhus is a medieval stone fortress located near Lake Åsunden that served as a residence for the Stenbock family. Its interior features Renaissance rooms with grisaille wall paintings and a baroque chapel on the ground floor that define the building's character.

The castle was built in 1470 by Arvid Knutsson as a defensive stronghold against Danish threats. Major renovations during the 16th and 17th centuries transformed its appearance and function over time.

Torpa takes its name from the estate that became the Stenbock family's main seat, held since the 15th century and never sold, passing through both male and female lines. Catherine Stenbock, third wife of Gustav Vasa, was brought here from Torpa. Since the late 1990s the Torpa Slottsteater performs outdoors below the fortress each summer.

Guided tours of the castle run from May to August; outside that season the interior is not shown. The building stands west of Lake Åsunden, about 25 km east of Borås, with the Torpanäset nature reserve just east of the stone house. The castle theatre performs outdoors below the fortress each summer.

The castle kept its original wooden walls for centuries, though they were temporarily removed in the 19th century when the building served as a grain storage. This practical conversion left marks on the structure that visitors can still observe today.
