See main article: Hamangia culture. In 1953, archaeological excavations on a site along the Lake Golovița, near Baia, led to the discovery of a new Middle Neolithic culture, named after the commune. Further research has shown that the culture, with Mediterranean origins, extended across Dobruja and North-Eastern Bulgaria. The culture's most notable artefact is an anthropomorphic statuette in terra cotta, known as The Thinker, which was discovered at Cernavodă.
