In 1785 Étienne-Louis Boullée designed Newton’s Cenotaph. Basically, the building is a large sphere that represents both the land and Newton’s discoveries. Its access can be gained through the base and, despite its size, only a small area of such base can be occupied. Its surface is skillfully perforated, so that sunlight can enter during the day and create the picture of night sky. At night a great source of artificial light in the centre portrays the daytime image.
The building is a manifestation of space on earth.
