The unique Kalochori Lagoon on Thessaloniki’s western outskirts, a landscape shaped by immigrant communities, industrial growth, and the gradual emergence of a wetland as a result of land subsidence, groundwater depletion, and the mixing of river and sea waters. Now part of the Axios Delta National Park, the lagoon is rich in rare biodiversity, hosts more-than-human activity, and participates in contradictory narratives of “symbiotic living” as the city inexorably expands to this side too.
