Córdoba has two UNESCO World Heritage Sites. The first is the Historic Centre of Córdoba: the Mezquita-Catedral was inscribed in 1984, and the surrounding historic centre (including the area of the Roman Bridge, Alcázar, and Judería) was added in 1994. The second is Medina Azahara (Madinat al-Zahra), the ruined Caliphal palace-city, inscribed in 2018. The Alcázar, Roman Bridge, and Synagogue fall within the Historic Centre inscription rather than as individually listed sites. Separately, Córdoba's Patios Festival was inscribed on UNESCO's Intangible Cultural Heritage list in 2012.
