Dôme de Barcellona Pozzo di Gotto, Minor basilica in Barcellona Pozzo di Gotto, Italy.

The Basilica of St. Sebastian is a Latin-cross church with a 23-metre-high central nave and a façade modelled on Sant'Andrea della Valle in Rome, built 1932–1935 by engineer Francesco Barbaro with the Fratelli Cardillo firm. Its dome follows Juvarra's Superga design, and the four façade niches hold statues of Saints Peter, Paul, Francis and Catherine by Domenico Farina.

The current building was started in 1932 after an earlier church from 1606 was severely damaged by the 1908 earthquake. The reconstruction under engineer Francesco Barbaro represented a major effort to restore the community after this disaster.

The cult of Saint Sebastian took root in the village of Barsalona, west of the Longano stream, around 1500, replacing Saint Nicholas of Bari as patron. The name Sebastian comes from the Greek "Σεβαστός", meaning worthy of honour. The church keeps an altar of Our Lady of the Dying, with an altarpiece by Filippo Jannelli painted around 1655, brought from the nearby Chiesa degli Agonizzanti.

The basilica sits in Piazza Duomo facing Via Roma, placing it at the town center and making it easy to locate. The site is walkable and welcomes visitors during regular opening hours.

The church is not a bishop's seat: Barcellona Pozzo di Gotto has no diocese, so the "duomo" is a title of honour, not a cathedral. Its papal bull of 9 November 1989 from John Paul II is set in marble in the first bay of the right aisle.
