If only the ageing walls of San Michele Castle could talk! But as they can't, inquire if tours are available to hear a few of its tales instead.
This fortified complex is situated in Cagliari, a place that has so much going for it! Bastion of Saint Remy, National Archaeological Museum, and Roman Amphitheatre of Cagliari are other fine sightseeing options nearby when you're all done at San Michele Castle.
