Central and bustling, Puerta del Sol is one of Madrid's best known squares. Several busy historical streets, such as Calle Mayor, Calle Arenal, Calle Alcalá and Calle Preciados, converge here and it contains several of the city's best known landmarks.
One of these is the famous clock at Casa de Correos, the headquarters of the regional government of Madrid. On 31December each year thousands gather in front of the clock and follow the tradition of eating twelve grapes as it strikes twelve, in a televised ceremony viewed by millions of Spaniards.
In the same place, opposite the Casa de Correos doorway, is the plaque marking Kilometre Zero, the point from which the country’s radial roads are measured and alongside which many Spanish tourists have their photos taken every day. The Puerta del Sol also contains the statue of the Bear and the Strawberry Tree, much loved by locals and a popular meeting point. The same image appears on the city's coat of arms.
On the opposite side, at the entrance to Calle Arenal, is the "Mariblanca" statue of Venus, a replica of the seventeenth century original that used to adorn a fountain located here, now held at the Casa de la Villa. Very near to the statue, in the centre of the square, is the equestrian statue of Charles III, the king who modernised Madrid in the eighteenth century with a series of improvements to the city's infrastructure.
