Corridonia is home to Fonte Oliva, a fountain that channeled a unique kind of medicinal water. The fountain was built by Giovanni Guiduccio in 1605 and today is characterized by a brick facade divided by two arches and equipped with an ancient settling tank.
Fonte Oliva was built as a public fountain but it was frequently used for medical purposes. Its waters seemed to be particularly beneficial for animals as well as to cure various skin conditions in men. Since many people found benefits from these waters, a masonry seat was set up inside the fountain basin to allow the sick to be treated.
Corridonia is rich in hydraulic architecture, among which we can also mention Fonte Pietromuto, made of brick and nestled against a hill; the fountain once functioned as a bath house thanks to its large basin and round arches. Worthy of mention is also Fonte del Mascherone. Known as early as 1587, the spring has the structure of a temple-shaped fountain with an engraving on its main facade. It is characterized by three mascarons: water used to flow through their mouths after being collected in communicating pools.
In addition, in the area near the Abbey of San Claudio, it is possible to find the ancient Mulino Franceschetti. Although today this watermill is no longer active, its imposing walls are still visible, as a symbol of the stories and traditions of the Cistercian monks who built it.
