2022
Its name is due to a fortress that was erected in the confluence between the streets Montera and Carretas during the War of the Communities (1520), whose main door had drawn a sun.
One of the reasons why the door of the Sun is best known is because of this square is born the network of radial roads of the state. To accurately identify this point there is a Zero Kilometer Plate on the sidewalk next to Post House, with the map of Spain.
Another must visit in Madrid friends 😉
