Philip II's chair is not only an exceptional viewpoint, where you can enjoy wonderful views of the greatness of the Monastery of San Lorenzo de El Escorial and its beautiful surroundings. It is also a piece of history as it was the place where Philip II watched the original building of his monastery.
Following Bailén Street past the Royal Palace and Viaduct, you arrive at Las Vistillas Viewpoint, where you can contemplate the unbeatable views of the Almudena Cathedral, Casa de Campo, and, on clear days, the Sierra de Guadarrama mountains, which were the Christian-Moorish front during the Moorish Invasion. Las Vistillas was used as a look-out during those days to keep track of the advancing Moorish troops.
From Mount Abantos, after a good snowfall, you can see the beautiful landscapes like the ones in photos, and you can also get some exercise going down to San Lorenzo del Escorial to enjoy the impressive Monastery.
Driving along the M-614 from the town of Guadarrama to Navacerrada and approximately at km. 13,500 right in the pasture of the Swallow, you'll find an excellent vantage point from which you can see in all its intensity much of the Sierra of Guadarrama, right on your right-hand side.
The origin of the place's name comes from the nickname that it received from an old woman who lived in a road watchman's house in the area. The site has a small parking lot, a fountain from which I have never seen any water flow, and two excellent posters in two lecterns which indicate the names of the peaks and hills that can be seen from the site. From this very same spot you have an unparalleled view of Los Molinos, Cercedilla and Seven Peaks.
