The castle of Capodimonte boasts a wonderful view of the Bay of Naples. Built in the 18th century by Bourbon kings, it has been the royals' summer residence for a long time; today it hosts a museum which exhibits various collections, including masterpieces by Tiziano, Botticelli, Perugino, and Raffaello.

This masterpiece of Italian Gothic architecture is most famous for what it’s missing—a roof. The abbey was built in the late 1100s and has been a dramatic-looking ruin for centuries. It’s open to the sky now, but still feels grand in a stripped-back kind of way. Just up the hill, the Rotonda di Montesiepi is worth a quick stop too—inside you’ll find a sword embedded in stone, tied to the story of Saint Galgano.
