December 12, 2025, Puente Romano de Valdesotos

The Roman Bridge of Valdesotos, located near the hamlet of the same name in the Sierra Norte of Guadalajara, is actually of medieval origin, probably from the 12th century, with main use during the Middle Ages and converted as a passage to the Monastery of Bonaval.

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.

A beautiful stone bridge. The climb afterward is quite rocky, and you'll have to walk for a bit.
