Monterchi is known above all because it preserves the famous fresco of the "Madonna of the Birth" of Piero della Francesca (XVsec.).

The Madonna holds with boldness the left arm supported on the side rather to a hard-working woman of the valley of the Tevere that not to the mother of the Savior. But the look and the tenderness with which the right hand touches the edges of the dress, that it opens above the turgidity of the maternal womb, arouse then an inexpressible sweetness, almost a spell in attends him of the great event of the birth of Christ wanted for the salvation of the men.

L' ancient name of the town Mons Herculis certainly postpones the memory to ancient pagan rites that were celebrated in these places and of which trace has remained in also the life of the populations valtiberine up to the actual time. A recent study has in fact shown the to persist of a pagan rituality to be revealed with partial immersions in the Afro water of the stream from pregnant that with such rite they intended to give him a divine protection for the birth, to have abundant milk for the nourishment of the baby.
