The Monument to the Fallen of the Great War is the bronze infantryman throwing a hand grenade, a work by sculptor Bruno Galcotti, inaugurated on September 30, 1930, on Via della Chiesa.

In the green area to the south, you will find the memorial stone dedicated to the partisan Lido Duranti (1919–1944), an Orentano native who fell at the Fosse Ardeatine.

A curiosity from a village chronicle: in March 1959, the Monument square was excavated in search of the legendary treasure of the 19th-century brigand Orcino — the hunt ended up in the newspapers, but the treasure was never found.
