For a long time the existence of Lutetia, the ancient city at the origin of Paris, has used the myth.
Poets and historians of the Renaissance in search of ancient sources, have evoked legends about the birth of Paris. Others quoted Caesar describing the Gallic defeat of Parisii (-52) or Julian the Apostate praising the mild climate (360).
At the beginning of the 19th century, Europe was seized with a fever of exhumation from the past. In Paris, it is almost fortuitously, on the occasion of the general works of Haussmann that one digs in the sector of the historical center. There are Roman remains that confirm the existence of the mythical city.
At the beginning of the 1st century of our era, a Gallo-Roman city develops on the Seine
Lutece is crossed by a wide main road, the cardo. This north-south axis still exists partly under the new name of rue Saint Jaques
In the city, the streets were organized in a well-ordered grid. It is estimated the densest area to a square of only 500m side.
It is in this space that will be built the main facilities of the city: the forum, the baths, the theater, the bullring, ...
The streets were served by a supply and drainage network. The domestication of water was a specialty of Roman engineers. In Rome and throughout the empire, the countryside and cities benefited from improved river systems. To feed Lutetia the sources of the south of the Paris basin are captured in Wissous, and directed to the city by a 16 km long aqueduct.
