Arevaliello, next to the wall Historical milestone · Arevalillo de Cega, Comunidad de Villa y Tierra de Pedraza, Segovia Image of Arevalillo de Cega, not of the place itself. The village is cited in 1247 as Arevaliello, a place name that perhaps derives from the pre-Roman are-valon, beside the wall; the present name was fixed in the 1916 reform of the municipal gazetteer. 1247 y 1916 Photo: Malopez 21 (CC BY-SA 4.0) What to see and do in Arevalillo de Cega
