Designed by architect Secundino Zuazo Ugalde, construction began in 1933 and was finally completed in 1942, having come to a halt during the Civil War. Today's Nuevos Ministerios buildings largely maintain the style and forms of the original project. The complex has a large central area with large courtyards, fountains, and ponds, around which the different ministerial departments are arranged, along with a large arcade that runs along Paseo de la Castellana, which is one of the most characteristic features of this building.
