According to maps dating from 1643, the Concerca fountain was also known as "Funtana con archi" because it was fed by an aqueduct.
This fountain, located in front of the entrance gate to the Algajola fortress, is made up of two distinct parts, because they are not contemporary.

The oldest, a sort of large vaulted room (probably from 1777), surrounds a more recent neoclassical pediment facade, dated 1856.

A stone basin collects the water, deemed to be good, which the people of the village still come to draw.

Drinking water fountains: to reduce our consumption of plastic bottles, the Calvi Balagne Community of Communes has listed the drinking water fountains on its territory.
