London’s oldest bridge crossing the River Thames shares the name of the palace, cathedral and the one-mile city or borough where it is located: Westminster. The seven-arch, wrought-iron design was created by architect Thomas Page. The 820 foot span connecting Lambeth on the South Bank and central London on the North Bank was completed in 1862. You may wonder why it is painted green. It matches the color of the seats in the House of Chambers inside the Palace of Westminster seen in the background. This view of the Houses of Parliament is known as the River Front Façade.
