This extraordinary structure is one of Madrid's most eye-catching landmarks. Seeming to hover above the ground, the brick edifice is topped by an intriguing summit of rusted iron. On an adjacent wall is the jardín colgante (hanging garden), a lush (if thinning) vertical wall of greenery almost four storeys high. Inside there are four floors of exhibition space awash in stainless steel and with soaring ceilings. The exhibitions here are always worth checking out and include photography, contemporary painting and multimedia shows.
Caixa Forum's shop (mostly books) is outstanding. You can visit the shop without paying the entrance fee.
