What is the Spanish name for Madrid's famous New Year's Eve clock square?

Madrid’s famous New Year’s Eve clock square is called Puerta del Sol.

Puerta del Sol is one of Madrid’s best-known public spaces and the location of the clock whose midnight chimes accompany Spain’s twelve-grapes tradition. Crowds gather there to eat one grape for each principal chime, while millions more watch the event on television from home.

The square also has major civic and historical significance. It contains Kilometer Zero, the conventional starting point for measuring Spain’s radial roads, and the statue of the Bear and the Strawberry Tree, a symbol associated with Madrid. Its location in the center of the capital has made it a natural gathering place for public celebrations.

The clock became especially important because its broadcast standardized the national countdown. The preliminary sounds before the main chimes can confuse visitors, so experienced participants wait for the sequence that marks the twelve grapes rather than beginning too early.
