Visiting the crypt will take you through the varied historical layers of Paris, quite literally. Ruins and artifacts correspond to the following periods and civilizations:

The Gallo-Romans and the Parisii

Paris was first settled by a Gaulish tribe called the Parisii. Archaeological digs in the area in recent years have recovered coins etched with the names of the Parisii. During the reign of the Emperor Augustus, around 27 BC, the Gallo-Roman city of Lutetia, occupying the left bank (rive gauche) of the Seine. The present-day island known as the Ile de la Cite was formed when several smaller islands were artificially joined during the First century AD.

The Germanic Invasions

Paris's tumultuous history might be said to have really begun when Germanic invasions threatened Lutetia, bringing chaos and instability to the urban development for nearly two centuries, from the middle of the 3rd century AD to the fifth century AD. In response to these waves of invasions, the Roman Empire moved to build a fortified wall around the city (on the Ile de la Cite) in 308. This was now the de facto center of the city, with the left-bank development left in disarray and partly abandoned.

The Medieval Period

It may be considered "the dark ages" in modern thinking, but the medieval period saw Paris rise to the status of a great city with the development of Notre Dame Cathedral. Construction commenced in 1163. New streets were created in the area and buildings and churches sprang up, giving rise to the new medieval "site."

The Eighteenth Century

By the eighteenth century, however, the medieval structures were judged unsanitary, cramped, and too vulnerable to fire and other hazards. Many of these were subsequently destroyed to give way to buildings then considered to embody the height of modern urban development. The "parvis" was made bigger, as were several adjoining streets.

The Nineteenth Century

Modernization efforts peaked in the 19th century, when the Baron Haussmann enacted an overhaul of medieval Paris, destroying and replacing countless structures and streets. What you see now on the square and surrounds is the result of this overhaul.

Temporary Exhibitions

In addition to the permanent exhibition at the museum, the Crypte Archaeologique holds regular temporary exhibits.
