Which Spanish square hosts Madrid's famous New Year's Eve midnight countdown?

Madrid's famous New Year's Eve midnight countdown is held at Puerta del Sol.

The square is best known for the clock on the former post office building, now the headquarters of the Community of Madrid. At midnight, television viewers and crowds listen for the clock's twelve chimes and traditionally eat one grape with each chime. The ritual is known in Spanish as las doce uvas de la suerte, or the twelve grapes of luck.

Puerta del Sol is also a major civic landmark. It contains the Kilometer Zero plaque marking the starting point for Spain's radial roads and a statue of the Bear and the Strawberry Tree, a symbol of Madrid. The New Year's Eve gathering is broadcast nationally, making the square's clock one of Spain's most recognizable seasonal images. The grape custom is associated with the clock's chimes, not with twelve separate midnight bells in every Spanish town.
