The Cathedral of Saint Mary of the See (Spanish: Catedral de Santa María de la Sede), better known as Seville Cathedral, is a Roman Catholic cathedral in Seville, Andalusia, Spain. It was registered in 1987 by UNESCO as a World Heritage Site, along with the adjoining Alcázar palace complex and the General Archive of the Indies. It is the fourth-largest church in the world (its size remains a matter of debate) as well as the largest Gothic church. The Archbishop's Palace is located on the northeastern side of the cathedral.
