The Castles of Bellinzona

Bellinzona sits where the Ticino valley narrows to a bottleneck, and whoever held that gap controlled the route between Italy and the Alpine passes, which is why three castles rise here in a stepped chain up the hillside. Castelgrande stands on a rocky outcrop over the town, Montebello climbs above it, and Sasso Corbaro crowns the slope higher still, and from Castelgrande a great fortified wall, the Murata, once ran clear across the valley floor to block it entirely. Built and rebuilt through the Middle Ages, largely by the dukes of Milan before the Swiss took the valley, they form the most complete surviving example of late-medieval Alpine fortification, which earned them World Heritage listing. You can walk the ramparts, look down on terracotta roofs and vineyards, and feel the geography that made this small town matter so much.

What you actually see

• Castelgrande - the lowest and largest castle on its rock above the old town.
• Montebello - the middle castle with its double moat and keep.
• Sasso Corbaro - the highest fortress, with the widest view down the valley.
• The Murata - the surviving stretch of wall that once sealed off the whole valley floor.

When to go

April to October is mildest for walking between the three; Ticino is the warmest corner of Switzerland and summer can be hot on the exposed ramparts. Spring brings blossom on the valley slopes and autumn the vineyard colour. The castles keep seasonal hours, shorter in winter.

Honest expectations

The three sit at different heights and visiting all of them means a real climb, or a bus and lift for the upper two; many people do Castelgrande and Montebello and skip Sasso Corbaro. The interiors are fairly sparse, with modest museums, so the draw is the architecture, the ramparts and the views rather than rich collections. Bellinzona is a working town, not a resort.
