The patron saint of Castelmola is Saint George, celebrated on 23 April. The exact reason behind the choice of this saint is not known, but the devotion is believed to have very ancient origins. The church dedicated to him, built around 1450 near Punta San Giorgio, stands out for the sobriety of its architectural lines and for the uniqueness of its bell tower, made up of a short tower incorporated into the building and topped, at its corners, by four pyramidal pinnacles; it is reached through an exonarthex covered by a barrel vault, closed off by a fine wrought-iron gate. In the mother church, rebuilt between 1934 and 1935 over the pre-existing cathedral and dedicated to Saint Nicholas of Bari, the statue of Saint George is kept alongside other fine works of art, in a building that shows a mix of styles from Romanesque to Gothic, from Arab to Norman, with the side portal and choir arch remounted from the original 16th-century church.
From the town's main square, Piazza Sant'Antonino, a path leads to the ruins of Mola Castle, from which a belvedere offers views over the Ionian coast, Taormina, the sea and the Calabrian coast.
