Between 1997 and 2005, thanks notably to Mgr. Lustiger, six new churches were completed in Paris and in La Défense. In spite of the diversity of the architectural schemes (Architecture Studio, C. Callies and J- M Duthilleul, F. Hammoutène…) they share the same goal of visibility within the urban space without trying to be monumental, and a specific attention given to the conception of inner space in order to emphasize a participative liturgy. If we study the aesthetics in which the rite takes place, we may point out the importance dedicated to the symbolic dimension of space and of works of art in order to assist the faithful or the visitor in a spiritual progression in accordance with the sense of the construction and the specificity of a place of worship
