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 is the largest Gothic cathedral and the third-largest church in the world. It is also the largest cathedral in the world, as the two larger churches, the Basilica of the National Shrine of Our Lady of Aparecida and St Peter's Basilica, are not the seats of bishops.
