An early, and exceptionally large example was created between 1830 and 1838 by a British Army officer. William Siborne, and represents the Battle of Waterloo at about 7.45 pm, on 18 June 1815. The diorama measures 8.33 by 6 metres (27.3 by 19.7 ft) and used around 70,000 model soldiers in its construction. It is now part of the collection of the National Army Museum in London.
