It should have been laid out in a semi-circle and lined by buildings identical to that at N°6 by Servandoni. Yet there is sometimes a margin between the project and reality, which you can see when you come across this square, in the centre of which is a fountain (by Visconti). It is known as the "four cardinal points", representing Bossuet, Fénelon, Massillon and Fléchier. The north of the square has become the domain of luxury brands such as Yves Saint Laurent and Christian Lacroix.
