Ruine Göskon, Medieval castle ruin in Obergösgen, Switzerland

Ruine Göskon is a medieval castle built on a peninsula above the Aare River between Obergösgen and Niedergösgen. Visitors can still see sections of stone walls, defensive ditches, and a water storage tank on the site.

The site began as a fortified refuge during the Iron Age and was later developed into a castle. In the 13th century, the local lords moved away and built a new stronghold elsewhere.

The name Göskon appears in medieval records as Cozinchova, Gozequovon and Gozekon, and belonged originally to the castle and today's Obergösgen; Niedergösgen was still called Bötzach long after its own castle was built. The Aare toll known as Grundrühre and the escorting of ships on the river were still listed in 1458 as rights of the lordship of Göskon.

The site is freely accessible and sits right beside the Aare River with good views across the water. Wear sturdy shoes since the ground is uneven and paths down toward the river can be quite steep.

Excavations in the 1980s uncovered Bronze Age and Roman objects, showing that people lived here far earlier than the castle period. These discoveries prove the location held importance for thousands of years.
