Marble Arch was originally completed in 1833 as an entrance to Buckingham Palace. In 1850, the Palace was remodelled and the Marble Arch was dismantled and moved to its present position the following year. The surrounding area is now known as Marble Arch with the nearest underground (tube) station named after it.
There are three different configurations of arches including the fixed arch, the two-hinged arch, and the three-hinged arch. These configurations determine how stable the arch will be. Types of arches include the triangular arch, semi-circular arch, segmental arch, rampart round arch, lancet arch, equilateral pointed arch, and jack arch. Additional types of arches include the trefoil arch, horseshoe arch, three-centered arch, elliptical arch, inflexed arch, ogee arch, reverse ogee arch, Tudor arch, and parabolic arch.
