Rio della Querceta descends from the slopes of Montalbano, wedging itself in between the slopes hosting the hamlets of Santa Lucia and Mezzana (Faltognano), before reaching a point nearby the castle of Vinci and ending in the river Streda, just downstream of the castle. The watercourse runs through the lands where Leonardo's family had most of their farms. Along the paths that cross its course, we can still see some well-preserved mills whose structures may date back to the 16th century, and which Leonardo would certainly have had the opportunity to observe. On the same slope of Montalbano, in fact, not far from the gorge of La Querceta, Leonardo studied a system for damming the watercourses to create an artificial reservoir, demonstrating that he had a detailed knowledge of the orography and hydrography of the area. The mills of the ravine of La Querceta are included today by a system of paths that lead from Anchiano to the church of Santa Lucia a Paterno and Faltognano.
