The historic city centre reflects the rich Spanish history as the centre of colonial power. World-famous art collections are housed in monumental heritage buildings, flanked by contemporary interventions and surprising renovation projects. Transformation and repurpose seem to be unique to Spanish architectural practice, with the Archivo Regional, Matadero Madrid and the Serrería Belga as telling examples. The Museum of the Royal Collection also shows great sensitivity in the way it is embedded next to the Royal Palace and the surrounding gardens. Be amazed by the richness and layering of this cosmopolitan city.
