The Calahorra Tower (Spanish: Torre de la Calahorra) is a fortified gate in the historic centre of Córdoba, Spain. The edifice is of Islamic origin. The Tower of La Calahorra rises up at the south of the Roman bridge, the far end from the city centre. It is a fortified gate originally built by the Moors (Almohads) and extensively restored by King Enrique II of Castile in 1369 to defend the city from attack by his brother Pedro I the Cruel from the South. It was origionally an arched gate between two towers. Enrique II added a third cylindrical shaped tower connecting the outer two.
