Calahorra Tower
You start at the fortress that was built to guard the Roman bridge from the southern bank of the Guadalquivir. Its origins are Islamic, but what you see today is the work of many centuries. Look at the outer walls for the coat of arms of Castile and León: it dates from the 14th century, when the tower played a part in the civil war between the brothers Pedro I and Enrique II over the Castilian throne. Enrique won, and he gave the fortress a moat and a second tower, linked to the first by a drawbridge.
The tower first appears in the records in 1236, when Fernando III conquered Córdoba and the fortress stood in the way of his advance. Later a third tower was added and the three were joined by cylinders of the same height. Once gunpowder arrived, gun ports were cut into the walls, and in 1514 Queen Juana I ordered the barbican around the compound that gives it its present shape.
Its later life was colourful: a prison for nobles, a girls' school from 1863, a Guardia Civil barracks. In 1952 mayor Antonio Cruz-Conde secured the building for the city, and after restoration it reopened on 29 April 1953 with an exhibition marking 500 years since the birth of the Gran Capitán; Francisco Franco attended the opening.
Inside is the Living Museum of al-Andalus, opened in 1987. It charges entry and is worth it if you want the background of Muslim Córdoba before you walk into the old town; if you are short on time, the exterior and the view along the bridge are enough. From here it is 730 m, about 10 min, to the Alcázar de los Reyes Cristianos.
