Castelgrande
You start on the castle that has collected the most names. Castelgrande has also been called castel vecchio, the old castle, castello di San Michele and castello d'Uri. Keep that last one in mind: the other two castles on this loop also carried names of Swiss places for centuries, and once you have seen all three, the pattern tells its own story.
In 2000 UNESCO put Castelgrande on the World Heritage list, but not on its own. The inscription covers it together with Castello di Montebello, Castello di Sasso Corbaro and the city walls that link them. That is the logic of this walk: you are not visiting three separate monuments, you are following one defensive system from end to end.
Should you go in? Castelgrande charges admission, with a reduced rate for those who qualify. If you plan to see the inside of all three castles, buy the Fortezza Pass here rather than three single tickets. If your interest is the walls and the town more than castle interiors, you can skip the ticket and still walk the whole loop.
From here it is 850 m, about 13 minutes, to the Ramparts of Bellinzona. Around the start you will also spot Torre Nera and Torre Bianca.
