Cordoba, Spain: This city now has more UNESCO Heritage sites than anywhere in the world: CNN

Alcazar de los Reyes Cristianos: Cordoba may not be as on-the-map as Madrid or Barcelona, but its quiet beauty, as seen here in the Alcazar, a palace fortress dating back to the time of Arab rule, is reason enough to visit.

Mosque-Cathedral: Built between 784 and 786 as a mosque, it was established as a cathedral in the 13th century when the Christians conquered the city. It was Cordoba's first UNESCO World Heritage site (recognized in 1984). Click through the gallery for more pictures of glorious Cordoba:
