This formidable fort-palace dates to the 14th century when it was commissioned by King Alfonso XI and built over an earlier Moorish palace. It was Córdoba's main royal residence and it was here that Fernando and Isabel met Christopher Columbus in 1486. Inside, the highlight is a series of Roman mosaics, discovered under Plaza de la Corredera in the 1950s, while outside, the exquisite Moorish-style gardens are a joy to explore.
Nearby, you can visit the Baños del Alcázar Califal, the impressive 10th-century bathhouse of the Moorish Alcázar.
To see the Alcázar in a different light, a popular multimedia show, Noches Mágicas en el Alcázar (Magic Nights in the Alcázar; adult/child €6.50/free), is held here most nights. This had been temporarily suspended at the time of research, so check with the tourist office for the latest situation.
