Spectacular Place Dauphine
Not a square, but a triangle, this is an elegant slice of the Ile de la Cite of Paris. The cryptic beginning is a reflection of the serenity and formality of Place Dauphine.
"The Place Dauphine was laid out in 1607–10, when the Place Royale was still under construction. It was among the earliest city-planning projects of Henri IV, and was on a site created from part of the western garden of the walled enclave known as the Palais de la Cité (because the Capetian kings had lived there long ago, before the Louvre was built)."
