Right beneath the iconic forecourt of Notre-Dame Cathedral lies the Archaeological Crypt, one of Paris's most fascinating underground sites.
This immersive space showcases archaeological remains and artifacts discovered on site, tracing the history of Paris from the Prehistoric era to modern times.
It tells the story of Lutetia, the ancient Roman city that would become Paris, through stone foundations, streets, and even an ancient hypocaust – a Roman underfloor heating system once used in a wealthy home.
You'll see the evolution of the city through fragments of buildings, pottery, coins, and urban structures that illustrate the continuous human presence in this part of Paris for over two millennia.
A perfect visit for history lovers, archaeology fans, and anyone looking to discover the hidden layers of Paris.
