It's an exciting time for archaeologists. A team in France found a tomb dating back 2,500 years. They believe it's from the fifth century B.C.
A team has been digging at this site since October. They have dated it to the end of the first Iron Age... that's when man began to use metal in daily life.
Archaeologists say this is one of the largest recorded tombs for this period.They call it exceptional not only for its size, but also because of the quality.
The grave has Greek, and possibly some ancient Italian artifacts.
Archaeologists think a Celtic prince was buried here and he had with plenty of goods. Some of the finds include a bronze wine cauldron. They also found a chariot.
Researchers hope this site could help shed light on the Iron Age European trade.
