The Cathedral of Saint Mary of Burgos is a Catholic church dedicated to the Virgin Mary located in the historical centre of the Spanish city of Burgos. Its official name is Santa Iglesia Catedral Basílica Metropolitana de Santa María de Burgos. Its construction began in 1221, in the style of French Gothic architecture and is based on a Latin Cross. After a hiatus of almost 200 years, it went through major embellishments of great splendour in the 15th and 16th centuries. The cathedral was declared a World Heritage Site by UNESCO on October 31, 1984. It is the only Spanish cathedral that has this distinction independently, without being joined to the historic centre of a city or in union with other buildings, as in Seville. It is similar in design to Brussels Cathedral.
