when it was mentioned with the name Mumianula in a deed for farming concession by the bishop of Volterra.

Traces of it are found in the geographic maps drawn by Leonardo da Vinci.

It lived by means of the traffic from the Salt Road and its thermal waters, but during the 1900s it was abandoned, a victim of looters and plunderers. Most of its buildings have recently been restored, including the small Church of San Frediano, which was first named in 1258.
