The Swiss Castles Day invites visitors to discover the world of castles. Thun Castle is also taking part with a themed program.

Swiss Castles Day is the most important event organized by the Swiss Castles Association and takes place every year on the first Sunday in October. On this day, numerous castles and fortresses in all three language regions of Switzerland open their doors and offer a varied program for a wide audience, especially families. Every year, Castles Day has a special theme.

Thun Castle also takes part with its own program tailored to the annual theme. The detailed program for 2026 will be published in the coming months. Further information can be found at www.dieschweizerschloesser.ch or schlossthun.ch/veranstaltungen/agenda/
