What famous square hosts Madrid's televised New Year's Eve countdown?

Puerta del Sol hosts Madrid's televised New Year's Eve countdown.

At midnight, crowds watch the clock on the former post office building, now the headquarters of the Community of Madrid, and eat twelve grapes in time with its twelve chimes. The broadcast has made the square's clock one of Spain's most recognizable New Year's symbols.

Puerta del Sol is a central public square in Madrid and is also associated with Kilometre Zero, the traditional starting point for measuring Spain's radial roads. The New Year's gathering is sometimes confused with the celebrations at Plaza Mayor, another major Madrid square, but the famous clock and grape-eating countdown are specifically linked to Puerta del Sol. Large crowds and security measures can affect access during the event.
