Dating back perhaps to the 17th century and remodelled over the centuries, the Pescaia Spring still preserves the classic brick archway and original side mouths from which water from the springs in the mountains above Chianni could be drawn. In the immediate vicinity also stood brickwork wash-houses, large tubs where women came to wash their dirty clothes, unfortunately demolished on several occasions in the second half of the 20th century.
Today, the Pescaia Spring is no longer active, but it remains a charming garden thanks to the rich vegetation near the S. Donato stream, which makes this small park an oasis of coolness from the summer heat, as well as a location for civil weddings.
In the vicinity of the spring, the remains of several buildings, used as oil mills and millstones, are visible. These are small, family-run buildings on two floors: the ground floor or underground room where the horizontal wheel was located and an upper room accessible by an external staircase for the millstones. The small hydraulic mill became almost a symbol of the peasant civilisation and its self-sufficiency. They were often owned by wealthy local families who rented the use of the mill to farmers or millers for a fee. Today only four mills remain more or less visible, often in a precarious condition but still giving us a fairly clear idea of their structure and operation.
At the beginning of the 20th century, a grandiose two-storey mill with a quadrangular plan was erected under the Pescaia spring and its wash houses. The Counts Rasponi Spinelli who had taken over from the Ricciardi decided to build two hydraulic mills upstream of the small mills that already existed. A quality investment that would pay off in the years to come. Unfortunately, the invention of electricity led to the gradual decline of this structure from the 1930s onwards and its abandonment.
