La Fuentona natural monument, Natural spring monument in Soria Province, Spain.
La Fuentona is a natural monument in Soria Province where the Abión River emerges from underground, creating a circular pool of water. The lagoon sits within limestone formations and is surrounded by thick forests that extend to the water source.
The site attracted human settlements since the Bronze Age, as the constant water supply provided a vital resource for survival and development. Over millennia, permanent communities formed here, taking advantage of the water source and the natural resources surrounding it.
The spring holds a special place in local storytelling, with tales of hidden spirits and magic tied to its mysterious depths. The striking green color of the water and its sudden emergence from the earth have inspired artists and captured the imagination of the region's people.
A marked trail connects the parking area at Muriel de la Fuente to the spring, passing through forests and rocky terrain. Sturdy footwear is recommended since the path crosses uneven ground and areas near the water can be slippery.
Beneath the lagoon lies a complex system of underground caves and water-filled passages that descend deep into the earth below. This hidden network reveals the true scale of the natural phenomenon, which appears as just a simple spring at the surface.
