The Castles of Bellinzona are a group of fortifications located around the town of Bellizona, the capital of the Swiss canton of Ticino. Situated on the Alpine foothills, the group is composed of fortified walls and three castles named Castelgrande, Montebello and Sasso Corbaro. Castelgrande is located on a rocky peak overlooking the valley, with a series of walls that protect the old city and connect to Montebello. Sasso Corbaro, the highest of the three castles, is located on an isolated rocky promontory south-east of the other two. The Castles of Bellinzona with their defensive walls have been an UNESCO World Heritage Site since 2000.
The walls seem quite well preserved.
I am glad that it has been awarded as a UNESCO site.
