Puerta del Sol is the pulsating centre of Madrid, where the city's radial road network begins. This public square has been a focal point for centuries, hosting celebrations, protests, and daily life.
Look up at the Real Casa de Correos' clock tower: its bells herald the New Year, and the moment is broadcast nationally. For the best view of the square's energy, stand near the 'Kilometre Zero' plaque at the south side, then step into the narrow streets of the historic centre.
