Three Castles of Bellinzona
Ticino
The Three Castles of Bellinzona are a remarkable group of medieval fortifications located in Bellinzona, the capital of the Swiss canton of Ticino. Comprising Castelgrande, Montebello, and Sasso Corbaro castles, along with extensive defensive walls, the complex guards the vital Alpine passes that connect northern and southern Europe. Castelgrande, the oldest and largest castle, sits atop a rocky peak overlooking the valley and the old city. Montebello castle is perched on a hill above Castelgrande, while Sasso Corbaro, the highest of the three, stands on an isolated rocky promontory. These castles represent an exceptional example of fortified architecture in the Alpine region and have been recognized as a UNESCO World Heritage Site since 2000. The fortifications include massive walls that once enclosed the town, creating a formidable barrier controlling access through the valley. Their strategic location made Bellinzona a key military and trading hub from Roman times through the Middle Ages, with the castles evolving through various rulers including the Romans, Ostrogoths, Byzantines, Longobards, Franks, and later the Visconti and Swiss Confederates. Today, visitors can explore the well-preserved castles, medieval walls, and enjoy panoramic views of the surrounding Alpine landscape, immersing themselves in centuries of military history and architectural splendor.

History
The site of Bellinzona has been inhabited since the Neolithic era, but its strategic importance rose significantly during the Roman Empire when a fort was first constructed on the Castelgrande rock in the 1st century BC.
The fort was rebuilt and expanded in the 4th century AD as part of a defensive chain protecting northern Italy.
After the fall of the Western Roman Empire, control passed through Ostrogoths, Byzantines, and Longobards, each reinforcing the castle's military role.
In the early Middle Ages, Bellinzona was contested between emerging powers such as the Franks and the Bishop of Como.
The castles and walls were further developed by the Visconti family in the 14th and 15th centuries to secure control of the Alpine passes.
Eventually, the Swiss Confederates acquired the fortress, which remained a key defensive site.
The fortifications have survived in excellent condition, reflecting centuries of military architecture and political history in the region.
