What is the name of Champagne’s historic avenue lined with producer headquarters in Épernay?

Avenue de Champagne is the historic avenue lined with Champagne producer headquarters in Épernay.

The avenue is one of the best-known streets in the Champagne region. Major houses, including Moët et Chandon, maintain prestigious premises along it, while extensive chalk tunnels run beneath the town and store millions of bottles.

Its cellars are possible because Épernay stands over chalk formations that can be excavated into stable underground galleries. The avenue therefore combines a visible architectural showcase with a hidden production and storage landscape below ground.

Avenue de Champagne is not the name of a wine style, grape variety or legally separate appellation. It is a town street and cultural landmark. UNESCO included it as one component of the Hillsides, Houses and Cellars of Champagne World Heritage property in 2015.
