(1713–96). French architect. He worked under Gabriel, and between 1754 and 1770 helped to lay out the Place Louis XV (now Place de la Concorde), Paris. He published a work on the Orders of Architecture in 1767, and designed the basilican church of St-Louis, St-Germain-en-Laye in 1764, completed 1823–4, as well as the Cathedral at Rennes (1764–1844), both of which were important examples of Neo-Classicism in church design. His work influenced Thomon (e.g. Stock Exchange, St Petersburg).
