 In 1341 Acquaviva became under control of the city of Fermo and became a garrison against enemy territory, keeping coastal villages (San Benedetto in Albula) out of the reach of Ascoli.During the 4th century the village population grew, bringing its numbers to twice its original size.The eastern section of the village was built and named “Terra nuova” to separate it from “Terra Vecchia” which was the original settlement, just before the fortress.
