The Cathedral of Baeza, or in full the Cathedral of the Birth of Our Lady of Baeza (Spanish: Catedral de la Natividad de Nuestra Señora de Baeza) is a Roman Catholic cathedral. The site, like the land, alternated between mosque and church during 12th and 13th centuries. The apse still maintains Gothic tracery, but in the 16th-century a major reconstruction by Andres de Valdelvira in Renaissance-style created the present church. The church forms part of a UNESCO World Heritage Site with other monuments in Baeza and in the nearby city of Úbeda. The cathedral was one of 100 nominees to be voted as the 12 Treasures of Spain in 2007.
