The "Cathedral of Barcellona Pozzo di Gotto" or "Duomo of Saint Sebastian" or Duomo of Barcellona Pozzo di Gotto, exact full name "Minor Basilica of Saint Sebastian", is in Piazza Duomo and the main façade faces in Roma Street.
 It is the largest of the churches of Barcellona Pozzo di Gotto, Italy and in the province, second only to the "Cathedral of Santa Maria Assunta" Messina.
 The engineer Barbaro nephew of Monsignor Barbaro directs the work performed by the firm Fratelli Cardillo, collaborated in the construction of the "Shrine of Christ the King", a contemporary work of the Cathedral of Saint Sebastian.
The Metropolitan Cathedral of Saint Sebastian (Portuguese: Catedral Metropolitana de São Sebastião ) better known as the "Metropolitan Cathedral of Rio de Janeiro" ("Catedral Metropolitana do Rio de Janeiro )" or as the Cathedral of St. Sebastian of Rio de Janeiro ("Catedral de São Sebastião do Rio de Janeiro" ), is the seat of the Roman Catholic Archdiocese of São Sebastião do Rio de Janeiro.
 The cathedral is the See of the Metropolitan Archbishops of the city of Rio de Janeiro, Brazil.
 The church is dedicated to Saint Sebastian, the patron saint of Rio de Janeiro.
San Sebastiano fuori le mura (Saint Sebastian outside the walls), or San Sebastiano "ad Catacumbas" (Saint Sebastian at the Catacombs), is a basilica in Rome, central Italy.
 Up to the Great Jubilee of 2000, San Sebastiano was one of the Seven Pilgrim Churches of Rome, and many pilgrims still favor the traditional list (not least perhaps because of the Catacombs, and because the Santuario replacing it in the list is much outside the inner city).
St. Sebastian's School, St. Sebastian School, Saint Sebastian's School, or Saint Sebastian School may refer to:
Saint Sebastian is a 1570-72 painting of Saint Sebastian by Titian, now in the Hermitage Museum in Saint Petersburg.
Saint Sebastian Tended by Irene is an oil-on-canvas painting by Hendrick ter Brugghen dated to 1625.
 Now in the Allen Memorial Art Museum of Oberlin, Ohio, the piece depicts the Roman Catholic subject of Saint Sebastian being saved by Irene of Rome and her maid following his attempted martyrdom by the Roman authorities.
 An exemplary piece of the Italianate Baroque tendency in Dutch Golden Age painting, the painting employs dramatic uses of light and skillful chiaroscuro to depict its religious subject, evidence of influence from Caravaggio and Ter Brugghen's fellow Utrecht Caravaggisti.
Saint Sebastian is an early sculpture by the Italian artist Gian Lorenzo Bernini.
 Executed in 1617 and 1618, it features the Christian martyr Saint Sebastian pinned to a tree, his flesh filled with arrows.
 It is smaller than life size.
 The sculpture is part of the Carmen Cervera's private collection and is currently shown in the Museo Thyssen-Bornemisza in Madrid.
