Unspunnen Castle

Unspunnen Castle is a fortification with a central round tower and sections of ring walls positioned on a rocky elevation near Abendberg mountain. The structure displays the typical features of a medieval stronghold with its defensive layout still visible in the remaining walls and foundations.

The castle was built in the early 12th century and served as a strategic point to guard the medieval Luchinen bridge near Gsteig close to Interlaken. After changing hands among noble families, the city of Bern took direct control over the property in 1529.

The meadow beside the ruins hosted the first Unspunnen Festival in 1805, where people gathered for traditional Swiss competitions and customs. Today this setting recalls folk celebrations that shaped local identity across generations.

You can reach the ruins through the Castle Path connecting Unspunnen to Rothenfluh, with free access available year-round. The trail is well-marked and offers views of the surrounding landscape from several points along the route.

The site was home to the first organized alpine competitions where wrestlers, stone throwers, and other athletes displayed their skills. This tradition of sporting events left a lasting mark on the region and continues in various forms today.
