From outside, Alhambra's red fortress towers and imposing walls rise from woods of cypress and elm, with the Sierra Nevada forming a magnificent backdrop. Inside the marvellously decorated emirs' palace, the Nasrid Palace and the Generalife gardens, you're in for a treat. Water is an art form here and its sounds take you into another world. Book in advance.
Museo del PradoConverted in 1819 from a natural history museum to a repository of Spanish art held in royal collections, the Museo del Prado hosts over 7000 works. The strongest collections are the 17th- and 18th-century Spanish paintings on the 1st floor, featuring the likes of Velázquez, Goya and da Ribera.
ToledoToledo is known as La Ciudad Imperial (the Imperial City) for a reason; this is Iberia's Rome with a cultural slug of mosques, synagogues, churches and museums. Toledo's labyrinthine narrow streets, plazas and inner patios are reminiscent of the medinas of Damascus and Cairo. Stay until dusk, if you can, when the streets take on a moody, other-worldly air.
AlcázarRapunzel towers, turrets topped with slate witches' hats and a deeeeep moat at its base make Alcázar a prototype fairytale castle, so much so that its design inspired Walt Disney's vision of Sleeping Beauty's castle. Fortified since Roman days, the site takes its name from the Arabic al-qasr (castle) and was rebuilt and expanded in the 13th & 14th centuries.
La Sagrada FamíliaIf you only have time for one sightseeing outing, this should be it. Temple Expiatori de la Sagrada Família (Expiatory Temple of the Holy Family) inspires awe with its sheer verticality and, in the true manner of the great medieval cathedrals it emulates, it's still not finished after more than 100 years.
