The deserted village of Castellanos de la Sierra Curiosity · Arévalo de la Sierra, Almarza, Soria Image of Arévalo de la Sierra, not of the place itself. Besides Torrearévalo and Ventosa de la Sierra, annexed in 1966, the municipal district holds the deserted village of Castellanos de la Sierra and the hamlet of the acebal itself, today without permanent residents. Castellanos de la Sierra was its own municipality until the mid-19th century, when it was merged into Arévalo de la Sierra; in 1528 it had only eight taxpaying family units, and in 1842 the census recorded eight households and 32 residents. It had already become uninhabited by the 20th century, although the ruins of its hamlet can still be seen. Its district also contains the castro of El Castellar, or El Castillo, a settlement from the 4th to the 2nd century BC, oval in plan and covering around 18,000 square metres, the largest of all those studied in the entire province of Soria.
