The Rio Grande Basin is located about two kilometers from Amelia, nestled in the Monti Amerini area. The Rio Grande is a stream flowing into the Tiber, and the area is described as an urban river park and a site of naturalistic and landscape interest. Its historical importance depends mainly on two dams: the upstream dam, called Para, which formed the Lago Vecchio (Old Lake), and the downstream dam, called dei Finestroni or Ponte Grande. For centuries, this hydraulic system has guaranteed a water reserve for the territory and has powered mills for grinding oil and grain, still remembered along the course of the basin.

The structure has 26 steps carved into the volcanic rock, with a height of 8 meters in the upstream part and 16 meters in the downstream part. It is believed to have been an Etruscan rock altar, probably dating back to the 6th-7th century BC, although some hypotheses suggest even older origins.
