Bellinzona Castles
The three castles (Castelgrande, Montebello, Sasso Corbaro), the murata, and the borgo walls form the finest medieval fortified complex in the Alpine arc — UNESCO World Heritage since 2000. Built as the Swiss Confederacy's frontier defense against Milan, they physically embody the political-military boundary that shaped Ticino's cultural identity. The Fortezza Bellinzona foundation manages the site and publishes events on fortezzabellinzona.ch, including Rabadan carnival activities.
