The famous building located in Paris known for its glass pyramid is the Louvre Museum. The Louvre, originally a royal palace, became a public museum in 1793 and is renowned for housing one of the world's most extensive collections of art, including the Mona Lisa and the Venus de Milo. The glass pyramid entrance, designed by architect I.M. Pei and completed in 1989, serves as a modern contrast to the historic architecture of the museum while providing an iconic and functional entry point for visitors.
