Its history and main features include: Origin: Originally a quarry for the construction of the TEEM highway, it was later redeveloped as a wetland. Unique shape: Unlike traditional quarries, it has sloping rather than vertical banks. This design choice has favored the growth of submerged vegetation, making it an ideal habitat for birdlife. Biodiversity: Thanks to its structure, the oasis has become a hub for many bird species for nesting, resting, and wintering. Hydrology: The body of water is fed by the aquifer and experiences variations in level of up to 2 meters, reaching its maximum in summer.
