Sasso Corbaro Castle is one of the the three castles in Bellinzona, Switzerland.
Unlike the other two castles Sasso Corbaro is not integrated into the city walls. The first part of the castle was the north-eastern tower which was built in 1478 to close a gap in the defenses of the city. In 1479 a small garrison was moved to the tower.
The north-eastern keep currently has four stories, though no records exist of its original height and roof. It was used as a living area when the castle was occupied.
