Museo al Aire Libre

This fascinating open-air collection of 17 abstract sculptures includes works by renowned Basque artist Eduardo Chillida, Catalan master Joan Miró, as well as Eusebio Sempere and Alberto Sánchez, among Spain's foremost sculptors of the 20th century. The sculptures are beneath the overpass where Paseo de Eduardo Dato crosses Paseo de la Castellana, but somehow the hint of traffic grime and pigeon shit only adds to the appeal. All but one are on the eastern side of Paseo de la Castellana.
