Olonzac, chief town of canton and economic center of the community of communes of the Minervois, is inhabited by 1650 Olonzagais (es) and owes its name to the Latin Olentiacum

From the Neolithic, human activity was present on the lands of Olonzac, 48 meters above sea level. Evidenced by the oppidum Bassanel, dating from the sixth century before Christ.

A stone's throw from the Canal du Midi, Olonzac is today the economic heart of Minervois. Its weekly market on Tuesday morning is one of the most vibrant and colorful in the region.
With a green theater, a public garden, an archaeological museum and many local shops, Olonzac is a pleasant and typical town in a fertile plain and planted with vines.
