The exhibition In the Seine: found objects from prehistory to the present day, currently hosted at the Archaeological Crypt of the Île de la Cité, offers a profound curatorial exploration of Paris’s identity through its aquatic artery. By showcasing 150 artifacts recovered from the riverbed, the display moves beyond traditional archaeology to present the Seine as a living archive and a silent witness to the city's evolution. The curatorial theme centers on the intimate, enduring relationship between human civilization and the river, framing the water as a repository of both the mundane and the sacred.

Spanning millennia, the exhibition highlights the historical significance of the Seine from the earliest human settlements to the industrial age. Visitors encounter Neanderthal flint tools found at Clichy-la-Garenne, which represent some of the oldest traces of life in the Paris basin, and Gallo-Roman stone sculptures from the sanctuary of Sequana, the goddess of the river. The transition into the medieval period is marked by the presence of bronze age weaponry and votive offerings, such as the curious lead-alloy figurines known as chevaliers, believed to be tokens of faith left by 14th-century knights. These pieces underscore the river’s role as a site of ritual and spiritual deposit across different faiths and eras.

The emotional resonance of the display lies in its ability to humanize the distant past through lost or discarded fragments of daily life. From a 16th-century mascaron from the Pont Neuf to humble pilgrim badges and domestic waste, the objects evoke a sense of shared continuity. There is a haunting beauty in seeing ritual deposits of swords and battleaxes alongside architectural fragments, illustrating how the river has absorbed the city's triumphs, struggles, and transformations. This dialogue between the artifacts and the ancient foundations of the crypt itself creates a powerful atmosphere of immersion, reminding us that the history of Paris is inextricably tied to the currents of the Seine.
