November 23, 2025, Castillo de Buitrago del Lozoya y Murallas

The Castle and Walls of Buitrago del Lozoya, one of the most important medieval sites in the Community of Madrid: The town has pre-Roman roots and was mentioned by Livy as a Celtiberian fortress (Litabrum). Muslim Fortification: Between the 8th and 11th centuries, the Muslims built the wall to protect the territory. Reconquest: Alfonso VI conquered it in 1085, and it passed into Christian hands. Current Castle: Built in the 15th century by the Mendoza family, during the reign of John II of Castile. Historical Uses: Noble residence, defensive stronghold, and setting for events such as the imprisonment of Juana la Beltraneja.

Beautiful town in La Sierra de Madrid with extraordinary landscapes. We recommend this town and its surroundings to isolate yourself from the world.

The Puentes Viejas reservoir is located in the middle course of the Lozoya River, in the Sierra Norte (Madrid). It belongs to the Canal de Isabel II reservoir network and is the third reservoir in the direction of the current that the river passes through.

On the Puebla de la Sierra highway you come across this viewpoint over the Puebla river gorge. The landscape is overwhelming. The vertical walls of bare rock stand before the green ridges of the mountains and the sky. It is an ideal place to immortalize with a photograph.

This town of just over 100 inhabitants owes its name to the number of oaks and cistus that populate the area. Within its municipal term is the unpopulated area of El Villar (from which one of the Lozoya reservoirs takes its name). However, currently nothing remains of this place.
