The church of Santa Maria in Faltognano belonged to the parish church of Greti since the 13th century, but the current building is the result of a radical 19th-century reconstruction. In the community of the church of Faltognano, some of Leonardo’s family’s estates stood, still recognizable today in the names of the small groups of farmhouses, such as La Noce, Il Capannile, and Podere Santa Maria. Leonardo must have known these places very well. On the Faltognano side, in fact, flowed the springs of some of the waterways Leonardo included in a project for the construction, downstream, of an artificial reservoir. Just below the church of Santa Maria flows the source of the Leonardian Rio di Lecceta, while a bit further to the east passed the Rio di San Lorenzo, all depicted by Leonardo da Vinci on the three maps dedicated to the project of the reservoir in the locality Serravalle in Val di Streda. These areas can easily be reached, by choosing, from among the "Paths of the Genius", the path "Anchiano, Santa Lucia, and Leccio di Faltognano", Or by choosing paths 10-14 and the connected local roads, on the municipality of Vinci’s "Hiking Trails Map".
