The spring basin holds approximately 12,000 cubic meters of water.
The water maintains a constant temperature of 11 degrees Celsius year-round.
It is considered the largest artesian well in Europe in terms of flow rate.
The octagonal structure was built to prevent the flooding of surrounding lands while ensuring irrigation for the Jiloca valley.
The aquifer supplying the spring is fed primarily by water filtering through the limestone mountains of the Sierra de Albarracín.
Fuente de Cella is the largest artesian spring in Europe and one of the largest in the world, with an estimated flow of 3,500 liters per second. The spring is contained within a large, octagonal stone basin measuring 130 meters in perimeter, constructed in 1729 to regulate the water flow. The water emerges from an aquifer located roughly 10 meters below the surface. This spring acts as the headwaters of the Jiloca River, which flows through the province of Teruel. The site remains a vital hydrological and historical landmark for the town of Cella, maintaining a constant temperature and flow rate throughout the year. The octagonal masonry work reflects 18th-century hydraulic engineering designed to manage water distribution for local agricultural use.

Walk the entire perimeter of the stone basin to observe the varying water clarity and currents.
Combine your visit with a walk along the Jiloca River path that starts near the spring.
Visit during the local festivals when the town square adjacent to the spring becomes the community hub.
Do not attempt to swim or climb into the basin, as it is a protected heritage site and a primary water source.
