One of the nicest looking castles in Europe is San Michele Castle, located in Cagliari, Italy. Visiting is one of the nicest things to do in Sardinia, and the best part of it is that, since it is not on the main tourist trail, it is actually very quiet. The castle surmounts the mountain that takes its name, and this location is perfect to admire gorgeous, 360 degrees views of the city. The castle was likely founded in the late 12th century, though it reached its peak importance between 1350 and 1511, when the Carroz, an important Spanish family, made it its residence. The castle had defensive functions: it has 3 main towers and used to be surrounded by a moat. It was abandoned in the early 17th-century and subsequently used as a sanatorium during the plague of 1652-1656, and later on again as a defensive point against French invasion. Nowadays, the castle can be visited throughout the year. It often hosts an art exhibition. The bonus for animal lovers is the protected cat colony that lives in the beautiful park that surrounds it.
