We stumbled upon this hanging garden in Madrid at the Caixa Forum. Designed by botanist Patrick Blanc and filled with over 15,000 plants-lovely! The building-designed by Herzog & de Meuron, also known for The Nest at the Beijing Olympics-was pretty incredible, and the free exhibitions inside about Miquel Barceló (elephant sculpture is his too)-one of Spain's best contemporary artists-was fantastic too. Stop by if you're in Madrid.
