Old maps indicate that it may have been a lagoon (blue arrow), in the Landes sense of the term, that is, a depression overflowing with water from the Bacqueyron stream in winter and which can dry up in summer. Near a noble house, the pond must have served the purpose of creating a mirror of water that embellished the landscape, without neglecting agricultural and domestic uses: a cattle watering trough and a washhouse.
This elongated pond covers approximately 6,000 m². In 2005, it was drained, cleaned, and refilled with water. The edges have been planted to provide additional shade for the three majestic bald cypress trees that welcome you at the entrance to the promenade. Come back in November when they will have donned their flamboyant autumn colors. A few million years ago, these cypress trees were abundant along the shores of the Aquitaine Gulf of the Miocene Sea. Buried under tons of alluvium, entire trunks were found at the bottom of the Arjuzanx mine.
Pneumatophores, or aerial roots, curiously emerge from the banks. Access and parking areas have been created.
Finally, a trail, picnic areas, and footbridges have been created to accommodate visitors and anglers.
