The building is located near the hamlet of Ambra, along the Ambra watercourse. The mill remained active until the beginning of the second half of the 20th century and the channeling system of water for the functioning of the machinery is still clearly visible. The origin of the mill is very remote, according to some scholars it was built by the Abbot of the Abbey of San Pietro a Roti, as shown by a document dated 1132 in which count Guido Guerra I gave to the abbey the possibility of founding a mill in the river section between the castle of Ambra and that of Pogi.
Currently the building is completely ruined; from a preliminary architectural analysis, elements dating from the 15th century would seem to be present in the oldest parts.
The building needs an important restoration and redevelopment intervention for the public interest, with the creation of exhibition spaces.
