When planning their cathedral, the rulers of Seville had clear ideas and, according to tradition, they stated:
Let us make such a church that in the future they will consider us crazy.
In fact, with 115 m length and 76 m width, the Cathedral of Saint Mary of the See ( Spanish: Catedral de Santa María de la Sede) is the largest Gothic cathedral in the world. In terms of size it is the third largest church on earth after St. Peter’s in the Vatican and St. Paul’s in London. In 1987 it was registered, together with the Real Alcazar and the General Archive of the Indies, by UNESCO as a World Heritage Site.
