 Various aristocratic families in Italy and Spain, such as the feuding Piccolomini and Scialenghi Strozzi families, rotated possession of the village.The presence of walls, towers (now destroyed) and doors bear witness to Acciano's strategic importance as the connection between the Adriatic and Rome, an importance it would bear for centuries.The name Acciano (Hacciànë) was stabilized in 1028 as Accio.
