Nancy’s crowning glory is this grand neoclassical square and Unesco World Heritage Site. Designed by Emmanuel Héré in the 1750s, it was named after the enlightened, Polish-born Duke of Lorraine, whose statue stands in the middle. Your gaze will be drawn to an opulent ensemble of pale-stone buildings, including the hôtel de ville and the Opéra National de Lorraine . Note, too, the gilded wrought-iron gateways by Jean Lamour and the rococo fountains by Guibal, including one of a trident-bearing Neptune.
