Of the 14th-century church of Sant'Alluccio with which the tower was associated, as described in the inventory of the municipality of Pistoia, there does not appear to be any trace in the late 16th-century maps of the Capitani di Parte Guelfa. In fact, in many maps, only the tower is represented, without any church. The indication that is usually associated with the drawing, torre di sancto alluccio, leaves no doubt about the identity of the building, the same turriform building we see today as a ruin in the 19th-century complex of the Counts Spalletti. Thus already in the 16th century, on the ridge of Montalbano around Vinci, there remained only the tower from the old complex of Sant'Alluccio to indicate the ancient border that had, by this point, become merely the limit between different administrations. The tower drawn by the Capitani di Parte Guelfa, with its austere forms, interrupted only by narrow openings, seems to have the appearance it originally had. On one of the maps, next to the tower, we can read the name of the Ridolfi. This family of Florentine origin had many possessions in the area of Vinci, including several mills powered by the Rio di Balenaia, the estate of Ferrale near Anchiano, and probably also the tower of Sant'Alluccio. Leonardo drew it in the map of the Lower Valdarno RLW 12685 (santa lucco), but placed it on Montalbano in an incorrect position. We can also observe that the Sant'Alluccio depicted by Leonardo displays, at the base of its tower, a lower structure that—due to its similarity with the drawing of San Giusto al Montalbano (on the same map), as a church with a bell tower—would suggest the intention to represent a church complex with a tower. Today only the tower remains from the ecclesiastical complex, the same tower that Leonardo could have observed by climbing up the road leading from Anchiano to Bacchereto. Through the parts of the current ruin that are now lacking plaster, you can still see part of the original wall of what was once the tower of the Ridolfi, at one time the bell tower of the church of Sant'Alluccio.
