Kastelen Tower Ruins

Kastelen Tower is a medieval castle ruin in Alberswil that rises to about 21 meters high at an elevation of 651 meters. The structure displays characteristic features of medieval defensive architecture with preserved stone walls and foundations.

The tower was founded in 1252 and served as a strategic fortification to monitor and protect the surrounding areas in medieval Alberswil. The structure played an important role in territorial control of this region during the Middle Ages.

The tower holds the status of a Class A Swiss cultural property of national significance and is part of the broader Kastelen Cultural Landscape. The stone walls and foundations show how people lived and worked at this location during the Middle Ages.

Visitors can examine the external walls and foundations of the ruins, while access to internal sections remains restricted for preservation reasons. Sturdy footwear is recommended since the ground is uneven and weather conditions can be variable.

Ongoing archaeological excavations at this site reveal new information about medieval construction methods and the daily life of castle inhabitants. These continuing investigations make the location an important place for understanding the local medieval past.
