Overlooking the port from the bottom of the Ramblas, this monument to Christopher Columbus seems like just another statue - but you can actually go inside it. There's a hidden elevator that whisks you to the top, where there's a viewing gallery that gives you great views of the Barcelona city center.
The monument was added to the city for the 1888 Universal Exhibition to honor the point where Columbus disembarked when he returned from America. The statue is said to be pointing to the Americas, but Chris is actually pointing completely the wrong way. Perhaps a fitting tribute, as he's not exactly known for his great sense of direction.
