Alt-Thierstein Castle

Alt-Thierstein Castle are the remains of a medieval fortress on the eastern slope of Tierstein Mountain in the Aargau region. The ruins at about 600 meters elevation still show the foundations and stone structures from when it was inhabited.

The fortress first appeared in written records around 1082 as the main seat of a local noble family. In 1180 the rulers moved their residence to a new castle on a different hill in the area.

The location served as an important noble residence for centuries and shaped how power was organized in the valley below. The family that lived here influenced the surrounding communities through their decisions and authority.

The site is reachable on foot via a marked walking route starting from the village center that covers about 9 kilometers total. The path passes through cherry orchards and may be slippery in wet weather, so sturdy shoes are recommended.

Excavations in the 1930s uncovered everyday objects including tools, pottery, and wooden carvings that show how people lived here centuries ago. These findings reveal what daily life was like in a medieval noble fortress.
