Puerta del Sol, Madrid

The Puerta del Sol is one of Madrid's main hubs. The first buildings surrounding this area were begun in the 16th century, although the square assumed the importance it has today with the construction of the Casa de Correos post office building in 1768.

The square was completely transformed in the 19th century, and between 1857 and 1862 it took on its current appearance following the demolition of a number of buildings. This site, known as the 'kilometre zero' from which all radial roads lead out of Madrid, has witnessed many different historical events, including the Esquilache Mutiny in 1766, the resistance against Napoleon’s troops on 2 May 1808, and the coronation of Ferdinand VII in 1812.
