The Place d’Armes must be, above all, a great civic, green and urban space all at once. Its beauty is kept within its fantastic scale, which must be kept indespensably, and the links established with the Jura’s landscapes that can be seen from the Square.
A very simple geometrical procedure turns the Terrain de Jeu into a slightly concave surface. Thus, it builds paradoxical perspectives without diminishing its monumentality; it creates places with different uses without losing unity, it naturally incorporates the Jura’s distinctive the rocky landscapes into its edges, whilst it accomodates the essential architecture into the Square; as well as the meadow landscapes in its interior.
The rest, the Plataforme Urbanie, with distintive trees planted in it, is a paved surface where the plane of the ground of Yverdone’s historical center extends naturally over the Square. This is an activated space that created a strong contrast with the Terrain, and thus both feed off each other, reinforcing its visual and civic values.
