Castel Sant'Elmo
Sant'Elmo is the name of both a hill and a fortress in Naples, located near the Certosa di San Martino. Together, the structures overlook Naples and are the most visible landmarks in the city. The name "Sant'Elmo" is from an old 10th-century church, Sant'Erasmo, that name being shortened to "Ermo" and, finally, "Elmo".
