Vertillum is a Gallo-Roman site in the modern commune of Vertault in the Côte-d'Or department of eastern France.

Many of the objects found at the site are held in the nearby Musée du Pays Châtillonnais.

[2] A Gallic oppidum covering about 25 hectares (62 acres) originally occupied the site, surrounded by a stone wall and ditch.

Later it evolved into a Gallo-Roman settlement with the typical features of such cities: residential areas, a forum, baths, temple and administrative center.

The archaeological setting of the older discoveries was not recorded, so it is not possible to define a chronology of metal working at the site.
