The National Museum of Natural History has been called "the Louvre of the Natural Sciences." Its largest and best-known gallery is the Grand Gallery of Evolution, located at the end of the central alley facing the formal garden. It replaced an earlier Neoclassical gallery built next to the same by Buffon, opened in 1785, and demolished in 1935. It was proposed in 1872 and begun in 1877 by the architect Louis-Jules André, a teacher at the influential École des Beaux-Arts in Paris. It is a prominent example of Beaux Arts Architecture. It was opened in 1889 for the Paris Universal Exposition of 1889, which also presented the Eiffel Tower. It was never fully completed in its original design; it never received the neoclassical entrance planned for the side of the building away from the garden, facing Rue Geoffroy-Saint-Hilaire.
