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.

Its name means Land of Dominion. Traditional houses, with corral and hayloft, alternate in the center and the periphery of the town with more modern houses.

The surroundings of this Madrid town are an extraordinary place to go on a bike route, especially during autumn, due to the abundance of deciduous trees.
