The Tower of Calahorra (Arabic: qala’at al-Hurriya) is a fortress of Islamic origin conceived as an entrance and protection of the Roman Bridge of Cordoba (Spain). It was declared a Historic-Artistic Site in 1931, together with the Roman bridge and the bridge door. It is part of the historic center of Cordoba that was declared a World Heritage Site by Unesco in 1994.
The tower, which rises on the left bank of the Guadalquivir river, was reformed by order of Enrique II de Trastámara to defend itself from its brother Pedro I of Castile. To the two existing towers, a third one was added, all of them being joined by two cylinders with the same height as those.
Later it was ceded to the Institute for the Dialogue of Cultures (Fundación Roger Garaudy) who has installed an audiovisual museum. The Alive Museum of Al-Andalus presents a medieval cultural apogee of Cordoba, from the ninth to the thirteenth century, based on the coexistence of Christian, Jewish and Muslim cultures.
