French architect.
He was trained by Étienne-Louis Boullée and won the Academy of Architecture's Grand Prix de Rome at age 19. His Saint-Philippe-duRoule (1764), Paris, was influential in reviving the basilica plan as a standard for European churches; it is characterized by a simplicity of design in stark contrast to the complex interiors of existing Gothic and Renaissance churches of the time. Chalgrin died before finishing his masterpiece, the Arc de Triomphe .
