Most of Madrid subway stations are made in granite, following the original design of an Spanish famous architect, Antonio Palacios. He also designed the stations entrances with the already familiar iron banisters. And some sculptural syubway entrance gates, very famous, such as Puerta del Sol and San Luis in Gran Vía street.
Granilouro designed, produced and installed these new subway entrances in most of Madrid underground network. Our kerbstones have been adapted to the streets around the stations and even to the stairs. Always following the original design of the Architect Palacios.
