The Santiago de Compostela Archcathedral Basilica (Spanish and Galician: Catedral Basílica de Santiago de Compostela) is part of the Metropolitan Archdiocese of Santiago de Compostela and is an integral component of the Santiago de Compostela World Heritage Site in Galicia, Spain. The cathedral is the reputed burial place of Saint James the Great, one of the apostles of Jesus Christ. It is also among the remaining churches in the world built over the tomb of an apostle, the other ones being St Peter's Basilica in Vatican City, St Thomas Cathedral Basilica in Chennai, India, and Basilica of St. John in İzmir, Turkey.
The archcathedral basilica has historically been a place of Christian pilgrimage on the Way of St James since the Early Middle Ages and marks the traditional end of the pilgrimage route. The building is a Romanesque structure, with later Gothic and Baroque additions.
