A visit to Doria Castle makes history fun. Gaze up at its time-weary walls and pull out your guidebook for some insight into its legendary past.
You'll have no end of sightseeing choices when in Castelsardo Historic Centre. Doria Castle is a good place to begin here, but there are loads of other fine places to consider. Elephant Rock, Baia delle Mimose Beach, and Baja Ostina Beach are not far from the fortified complex and will fill in your day nicely.
