Dans la Seine exhibition presents 150 objects collected from the river testifying to its history and its populations. Fallen, thrown away or lost, they are either the result of “fortuitous discoveries during the dredging of the river” or the result.
The Crypt houses the Gallo-Roman remains discovered under the square in the 1960s, including the quay of the first port of Lutèce. From medieval times, the river spat out lead figurines, a set of thimbles, a promise ring, miniature crockery.
