Puerta del Sol
You start at Km 0. Puerta del Sol is the point from which Spain's radial road network is measured, and it is one of the busiest squares in the city. Find the clock on the old House of the Post Office: its bells mark the start of the new year, when Spaniards eat the Twelve Grapes, and the countdown from here has been broadcast live on radio and television since 31 December 1962.
The name goes back to a gate. In the 15th century Madrid was ringed by a wall, and one of its gates faced east and was decorated with a rising sun, hence “Gate of the Sun”. Between the 17th and 19th centuries the square was the place to hear news: couriers from abroad and from all over Spain arrived at the Post Office here. The Gradas de San Felipe, by the church of Saint Philip, were one of the city's great mentideros. The word sounds like “lie factory”, but it comes from mentar, to talk about someone, so think of it as a gossip corner.
The Post Office building was designed by the French architect Jacques Marquet between 1766 and 1768. Under Franco it housed the Ministry of the Interior and State Security, a dark address for many Madrileños; today it is the seat of the President of the Madrid Community. The square has stayed political: people gathered here after the 2004 train bombings and against the Iraq War, and on 15 May 2011 protesters set up camp in the middle of the plaza, the start of the anti-austerity movement that spread through social media.
There is nothing to enter, so ten minutes is enough. From here it is 400 metres, about six minutes, to Gran Vía.
