Marble Arch is a large, white marble monument located in London, England. Designed by architect John Nash, it was originally built in 1827 as a grand entrance to Buckingham Palace. The structure features a neoclassical design with three large arches and is made from Carrara marble. In 1851, Marble Arch was moved to its current location at the northwest corner of Hyde Park. It serves as a popular landmark and is often used as a meeting point for locals and tourists. The monument is also near Oxford Street, one of London's busiest shopping areas.
