Just south of the monastery, Real Monasterio de San Lorenzo, is the Huerta de los Frailes , which merits a stroll, while the Jardín del Príncipe , which leads down to the town of El Escorial (and the train station), contains the Casita del Príncipe , a little neoclassical gem built in 1772 by Juan de Villanueva under Carlos III for his heir, Carlos IV.
