Low Valley of the Lozoya
The town of Serrada de la Fuente was a former municipality in the province of Madrid, with capital in Serrada de la Fuente, that in 1975 merged with the municipalities of Paredes de Buitrago and Mangirón to create the municipality of Puentes Viejas.
According to various sources its place name could be related to "sierra", alluding to the location of the first houses in the village, in a Gorge in the mountains of the dead woman, surrounded by mountains and streams.
During the Middle Ages, Serrada de la Fuente was linked to the Community of the Villa and Land of Buitrago and subsequently, to the Lordship of Buitrago. After the disappearance of the Lords, this place ceases to depend on Berzosa and forms its own Town Hall.
From Serrada we highlight its Church, dedicated to St Andrew the Apostle, and their foal and laundry that still remain as a traditional souvenir.
