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.

The Port of Navafría is one of the entrances to the famous Horizontal runway that connects this port with the historic port of Somosierra. The Port of Navafría is located between the municipalities of Lozoya and Navafría. With its 1,773 meters above sea level, it is considered a first-class port in the “Cycling Tour of Spain”. This natural area is made up of a lush oak forest in the lower part and a beautiful pine forest in the upper part.
