Etienne-Louis Boullée was an influential 18th century French architect known for his abstract geometric style inspired by classical forms. He removed unnecessary ornamentation and inflated geometric shapes to a large scale with repeating elements like columns. His drawings included projects for public buildings such as churches, palaces, and theaters that emphasized regular shapes through symmetry, order and proportion to create a sense of grandeur, beauty and harmony. He also designed cenotaphs and cemeteries meant to evoke dark and somber feelings through sparse, bare walls and shadows.
