Spectacular and reviled in equal measure, Valencia, Spain's City of Arts and Sciences has proved to be the proverbial gift that keeps on taking. Despite a budget that quadrupled to over €1 billion, the huge museum and arts complex, completed in 2005, just never attracted the predicted stampede of visitors. Designed by Valencia-born Santiago Calatrava, the complex itself is filled with bone-like constructions that recall a gargantuan dinosaurs' graveyard. The cemetery comparison isn't actually that far off – as I've commented before, this was one of the sites where the Spanish boom years' trend for grand urban projects came to die.
