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.

"La Rupe di Marculo is a place located near Narni, in Umbria, Italy. This cliff is shrouded in a macabre legend that dates back to the 16th century. According to the story passed down, in 1568 a tragic event took place on this cliff. Francesco Cenci, a well-known Roman nobleman, threw a hermit named Marculo off the cliff. This act of violence gave rise to the legend that surrounds the place, making it a point of historical and cultural interest in the area.".
