One of Madrid's enduring symbols, it's made entirely of granite with one central arch and two smaller passageways on each side. Carlos III had his Court architect Sabatini build the gate in 1778 as a monument to himself and to show visiting merchants from Aragon how important the city had become. The ornamental statues are the work of Roberto Michel and Francisco Gutierrez. It's location is spectacular, as it stands on raised ground opposite another symbol of the city, Cibeles Fountain.
