The medieval fortress, of which only the bastions remain, is the best place from which to admire the panorama; inside is the Church of Santa Maria del Suffragio, currently deconsecrated, built in 1698 and enlarged at the end of the 18th century.

From the fortress you can also admire the former St. Michael hospital built in 1782 and the Autopalace, a liberty style complex, a former coach garage, now restored and converted into an exhibition space.
