At the beginning of the XVIIIth century, the " new Town " of Versailles was achieved and could not be extended any more.
A second town, completely pulled off from the 1st one, was going to be erected on the spot of the ancient " Parc aux Cerfs " (park of stags) of Louis XIII. It's the Saint Louis area.
Its ground, divided into plots like a draughtboard, spreads itself out around its magnificent cathedral and its picturesque squares.
