In the nineteenth century, historical reenactments became widespread, reflecting the then intense romantic interest in the Middle Ages. Medieval culture was widely admired as an antidote to the modern enlightenment and industrial age. Plays and theatrical works (such as "Ivanhoe", which in 1820 was playing in six different productions in London alone) perpetuated the romanticism of knights, castles, feasts and tournaments. The Duke of Buckingham staged naval battles from the Napoleonic War on the large lake on his estate in 1821, and a reenactment of the Battle of Waterloo was put on for a public viewing at Astley's Amphitheatre in 1824.
