Walking around the interior of this building, you'll soon see where the some of the £414 MILLION went. £414 MILLION?!? How is it possible to spend that amount of money one one single building? Well, it is verrrry swanky inside... with the interior comprising of marble and wood. Very nice indeed. Architect Enric Miralles actually passed away before the building was completed (yes, it took that long to build). The panoramic below is a bit wobbly, but gives y'all an idea of how large & swanky it is :)
