The archaeological crypt of the square of Notre- Dame :

The discoveries made at the time of excavations undertaken in 1965, at the time of the construction of a car park under the square of the cathedral Notre Dame, are at the origin of the creation of the archaeological crypt.
Michel Fleury, vice-president of the Commission of the Old Paris man and then director of historical Antiquities of the area of Island-of-France, were the instigator. The crypt conceals many vestiges of installations and ancient constructions, of which a system of quay, houses with hypocauste, the rampart of the Lower Empire. The more recent periods are also represented, with for example the medieval wells, the cellars of houses of medieval origin or the foundations of the frontage of the old people's home of Child-Found built by Boffrand at the XVIIIth century
