Gallo-Roman ruins discovered at CMS dig site

As construction workers are preparing the work site for the CMS-detector cavern, they unearth 4th century Gallo-Roman ruins. The find delays work for 6 months while archaeologists excavate the site. 

The archaeologists find a Gallo-Roman villa with surrounding fields, as well as coins from Ostia (a seaport of Rome), Lyons in France (then Gaul) and London.
