Castles of Bellinzona

Stand still for a moment and listen. Somewhere below, a train slides through the valley, and church bells answer it from the old town. Under your hand, the stone is rough and grey, cool even on a warm afternoon. Look up, and the walls climb the hillside in long, broken lines, with battlements cut against the sky. This is Bellinzona. For centuries, these castles watched the valley floor.

The town sits in Ticino, the Italian-speaking canton of southern Switzerland. That explains the language you hear in the cafés and the warm colours of the houses below. It also explains why the castles exist. Bellinzona sits at a narrow point in the valley of the river Ticino. Here, routes from several Alpine passes come together before they continue south toward Lake Maggiore, Milan, and the plains of Lombardy.

Those passes matter for this whole story. The Saint Gotthard, the San Bernardino, and the Lukmanier all send their traffic toward this one gap. Merchants, pilgrims, soldiers, and mule trains carrying goods all came through it. Whoever held Bellinzona could watch them, tax them, or stop them completely. So the town became a lock on the door between northern and southern Europe, and these castles were the bolts.

There are three main castles, and each one has its own character. Castelgrande is the oldest and the largest. It sits on a rocky hill right above the old town. Montebello rises higher on the eastern slope, linked to the town by its walls. Sasso Corbaro sits highest of all, alone on a wooded ridge. Together with the walls between them, they form one of the most complete examples of medieval military architecture in the Alpine region.

Here is the first surprise. The rock under Castelgrande was a fortified site long before any of the walls you see today. Archaeologists have found traces of settlement here from prehistoric times, and the Romans also used the hill as a military post. The castle in front of you is the newest layer on a very old foundation. People have looked out from this rock across the valley for thousands of years.

Most of what survives today comes from the fifteenth century. In that period, Bellinzona belonged to the Dukes of Milan, first the Visconti family and then the Sforza family. They feared the Swiss Confederates to the north, a growing alliance of mountain communities. So the Milanese strengthened and extended the defences. They built higher walls, added towers, and turned three separate castles into one connected system.

The most unusual part of that system is the Murata, the great wall that runs from Castelgrande down across the valley. Originally, it reached all the way to the river Ticino. Think about what that means. The Milanese did not only defend a town. They tried to close the entire valley floor with stone. Any army coming from the north had to face this barrier, with soldiers on the castle hill above it.

The second surprise is that these defences did not stop the Swiss in the end. In 1478, Swiss forces beat a much larger Milanese army at the Battle of Giornico, further up the valley. Around 1500, Bellinzona passed into the hands of three Swiss communities: Uri, Schwyz, and Nidwalden. For about three centuries, each castle carried the name of one of those rulers. Castelgrande was the castle of Uri, Montebello was the castle of Schwyz, and Sasso Corbaro was the castle of Unterwalden.

Sasso Corbaro has its own story. According to the usual account, the Milanese built it in a matter of months, soon after their defeat at Giornico. They wanted to close a weak point on the high ground. It is smaller and more compact than the others, a square keep with a walled courtyard. From up there, the view opens wide over the valley floor. It is a fair climb, but many visitors say it is the quietest place in Bellinzona.

Montebello shows the clearest picture of medieval defence. Look for the layers. There is a central core, then rings of walls around it, then dry moats and a drawbridge at the entrance. An attacker had to pass one barrier after another. Walk the walkways along the top, and you can look down through the battlements, the gaps where defenders once stood. From here, the walls run down toward the old town like a stone ribbon.

Back at Castelgrande, look for the two towers on the hilltop. They are known as the White Tower and the Black Tower. The castle also shows how a historic site can meet modern design. In the late twentieth century, the Ticino architect Aurelio Galfetti restored the site. One of his best-known additions is a lift cut deep into the rock. It carries visitors from the square at the foot of the hill straight up into the castle.

That contrast is worth a pause. Inside the lift shaft, you see smooth concrete and clean lines. Then the doors open onto old walls and wide lawns. Some people loved this approach and others criticised it, but it changed how people think about restoring old monuments. In 2000, UNESCO added the castles, the walls, and the ramparts of Bellinzona to its World Heritage List. That status recognises the whole fortified system, not only one building.

Today, the castles do a quieter job. Families picnic on the grass at Castelgrande. Concerts and festivals fill the courtyards on summer evenings. Below, the old town has arcades, shuttered windows, and small squares where people sit with an espresso. The stone that once kept armies out now holds a calm everyday life. Walk the walls slowly, and you can still see how one valley shaped the history of a continent.

Before you move on, take one more look across the valley. Follow the line of the Murata with your eyes, from the castle hill down toward the river. Then look up to Montebello, and higher still to the small square shape of Sasso Corbaro among the trees. Listen again for the train below. It still follows the same old route between north and south.
