Visit the star-shaped military fortress of the Castel Sant'Elmo at the summit of Vomero Hill. Take in the fantastic views of Naples and its stunning surroundings from the rooftop. Explore the magnificent building at your own pace. Discover its interesting history, from the original church dedicated to St. Erasmus, to the current structure as a unique example of 16th-century military architecture carved into the city's famous tufa rock. Designed by the Viceroy Don Pedro Alvarez de Toledo and Pedro Luis Escriva, a military engineer from Valencia, the roof-top terrace covering the perimeter of the castle is without a doubt a stand-out feature. After enjoying the views over St. Martin's Charterhouse (Certosa di San Martino), admire the various views of the city and the gulf. Don’t miss the cultural activities and events that often enliven the spaces of the castle, from ancient art through to more contemporary styles.
