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.

Prádena del Rincón is a charming village located in the Sierra Norte of Madrid, founded between the 11th and 12th centuries and historically linked to livestock farming. Strolling through its streets reveals traditional architecture surrounded by nature. Its monuments include the Romanesque-Mudejar church of Santo Domingo de Silos. The tranquility of the area and its rural trails invite you to a peaceful and contemplative getaway in the heart of the Sierra del Rincón. This is ideal for those seeking a genuine connection with nature and rural history, far from the hustle and bustle, with routes that allow you to explore ancient transhumance trails and enjoy the area's biodiversity.

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.

Located on an old Muslim fortress reconquered in 1085 under the reign of Alfonso VI. The first testimonies of the castle come from the hand of Alfonso VII, who gave the properties to the dukes of Mendoza. These, in the s. XV, they would build a castle fortified by seven different towers, built with brick in the Mudejar style. The Marquis of Santillana and, later, Juana de Portugal and her daughter, Juana la Beltraneja, would reside there. During the War of Independence, the French would use the fortress as a barracks, fleeing from it in 1813, destroying it in their escape, then beginning its deterioration. It currently has a bullring inside and has been closed for restoration since 2016. It is a historical gem that should not be overlooked if you visit the Madrid town.

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.
