The tomb of an Iron Age Celtic prince has been unearthed in a small French town. The ‘exceptional’ grave, crammed with Greek and possibly Etruscan artifacts, was discovered in a business zone on the outskirts of Lavau in France’s Champagne region. The prince is buried with his chariot at the center of a huge mound, 130 feet (40 meters) across, which has been dated to the 5th Century BC.
