The Octagon supports the Royal Hospital Chelsea's distinctive cupola and lantern and rises to a height of 130 feet.
Over the north entrance are the Royal Coat of Arms from the Royal Hospital at Kilmainham, Dublin, removed when it closed in 1925.
The statue of a Chelsea Pensioner on the North Front, by Philip Jackson, was unveiled in 2000 to commemorate the Millenium. About the base is the soldiers' prayer, based on that said by Sir Jacob Astley before the Battle of Edgehill in 1642 - "O Lord you know how occupied I shall be this day. If I forget thee do not forget me".
