Madrid Community sits high on Spain's central plateau. There is plenty of superb scenery and good walking country in the sierras to the north, which are a refuge for city dwellers who go there to ski in winter or cool down during the torrid summers. In the western foothills of these mountains stands El Escorial, the royal palace-cum-monastery built by Felipe II, from which he ruled his empire. Close by is the Valle de los Caídos, the war monument erected by Franco. The smaller royal palace of El Pardo is on the outskirts of Madrid, and south of the city is the 18th century summer palace of Aranjuez, set in lush parkland. Historic towns include Alcalá de Henares, which has a Renaissance university building, and Chinchón, where taverns cluster around a picturesque arcaded market square.
