An important dig below Notre-Dame is speculated to be the "dig of the century" for it uncovered around 1,700 years of Paris history in the cathedral's forecourt.
Archaeologists hit Roman layers and found lots of stuff, such as a fourth-century coin, odd-marked medieval pottery, and old house remains.
These finds show how the Île de la Cité became a Roman area, then a medieval spot, finally ending up as Notre-Dame’s location.
This project gives researchers and visitors key original clues that change local history.
There are also cool chances for dating, keeping things safe, and showing it off to the public.What archaeologists found beneath the cathedral: Coins, pottery and Roman layersAccording to a press release by République Française, this excavation matters because it reveals a continuous record of human activity right in the heart of Paris.
