Riserva Naturale Regionale Sentina

Sentina area, near the border between the Marches and Abruzzi, has been a coastal area of great historical and geographical importance since ancient times. Historical and archaeological documents confirm that the river Tronto has united, and not divided, the two territories.
Such unity is witnessed by finds of structures dating back to the Roman Age that can be probably ascribed to the buildings and streets of the town of Truentum, thanks to the several inscriptions found, from studies and research regarding the settlement of pre-Roman populations in the valley.
Recent studies have also revealed commercial and cultural exchanges between the Mycenaeans and the local people in the 14th and 13th centuries BC.
