San Sebastiano, Baroque basilica in Melilli, Italy

San Sebastiano is a Baroque basilica in Melilli featuring three bronze entrance doors, with the central one showing the martyrdom of Saint Sebastian in detailed relief. The interior is designed with columns and a vaulted ceiling that are typical of Sicilian Baroque architecture.

A church stood near the Carcarella grotto before 1414, when a wooden icon of Saint Sebastian, said to come from a wrecked English ship near Stentinello, was brought here. The 1693 earthquake destroyed that north-facing building; only the wooden statue survived. Reconstruction began in 1695 under Francesco Rinaldi, Francesco Pattavina and Geronimo Palazzotto, and in 1702 the surrounding loggia was added.

The ceiling paintings by Olivio Sozzi (1759–1763) show the Glory of Saint Sebastian and the Virgin Mediator of All Graces, with medallions of the Triumph of Faith and Peace and Justice. Each side-chapel vault carries an allegory of a virtue, such as Fortitude or Chastity. The bronze portals by Domenico Girbino depict the martyrdom by arrows, with palm and crown symbols on the side doors.

The church stands on the San Sebastiano terrace beside Via Iblea, with the monumental Loggiato starting on the right side against the slope; two stone steps link the churchyard to the street. The facade faces the small piazza, and the town centre of Melilli lies just below. The bronze side portal by Domenico Girbino gives access beside the main doors.

The wooden icon of Saint Sebastian was said to have been rescued from a shipwrecked English boat near the bay of Stentinello and carried to Melilli in 1414. The church's facade design was later copied for the church of the same name in Middletown, Connecticut, because so many Melillesi emigrated there.
