Baeza, formerly also written as Baéza, is an Andalusian town in the province of Jaén in southern Spain. It lies perched on a cliff in the Loma de Úbeda, the range separating the Guadalquivir River to its south from the Guadalimar to its north. It is now principally famed for having some of the best-preserved examples of Italian Renaissance architecture in Spain. Along with Úbeda, it was added to UNESCO's list of World Heritage Sites in 2003. The former Visigothic bishopric of Baeza remains a Latin Catholic titular see.
