The enclosure of Carvin "La Gare d’Eau" belongs to the neolithic chrono-cultural group of Spiere. Located near the river Deûle, it encloses a hill surrounded by wetlands with  an well-organized system of concentric ditches and fences. These show frequent interruptions, according to a precise layout to create passages between outside and inside of the enclosure. Inside, along storage features, two buildings were identified. Archaeological features have yielded a considerable quantity of artefacts, especially ceramics.
