Diagonal Mar Park was opened in 2002 for the Forum of Cultures 2004. It was designed by EMBT architects Enric Millares and Benedetta Tagliabue and is divided into two parts - a rambla for walking and an area depicting the life of man. The park features a children's play area, a zigzag bridge over the lake, a green mountain with slides, the lake itself, and a central square.
