Spain 2008: .Torre Giralda, Sevilla
La Torre Giralda is the centerpiece of the city of Seville. It remains to this day the tallest structure in Seville, by law. The Giralda was built in 1198 and spent its early years as the huge single minaret of a Moorish mosque; it was so big, in fact, that it was the world's tallest structure at the time.
Conquering (and cathedral-building) Christians couldn't bear to tear down such a world-class tower, and instead incorporated it as a bell tower in their grand cathedral. Perhaps sensing the monumental Moorish tower would forever call their cathedral chump, the Christians built the medieval equivalent of the Mall of America: the Cathedral of Seville is the second-largest medieval cathedral in the world, behind only St. Peter's Basilica in Rome.
