Nine days in the Sardinian town of Cagliari in 1921 was all it took to inspire D. H. Lawrence to write one of the last century’s great travel narratives, Sea and Sardinia. Spend a night at the Lighthouse Capo-Spartivento, on the southernmost tip of Sardinia, and you may be inclined to pen a classic of your own. Set on an isolated promontory 350 feet above the Mediterranean, Italy’s first and only lighthouse hotel was built in 1856 by the Italian Navy, which still operates its third-story lantern. As for the floors below, owner Alessio Raggio has spent 20 years perfecting the place, filling the four barrel-vaulted guest rooms with Murano-glass chandeliers and enormous circular beds facing the sea. You can book one suite or take over the entire property (including two “apartments,” with ceilings made of glass, for better constellation viewing). Also on hand: three chefs preparing just-caught fish to order, a cistern turned cellar brimming with Sardinian wines, and untamed private beaches.
