These two beautiful historic graveyards sit in the heart of Hampstead Village. The earlier graveyard, adjacent to the 18th century church, dates from medieval times, and the more recent graveyard across the road dates from 1812. Many famous people lie in the graveyards, including the artist John Constable, clockmaker John Harrison (who invented the marine chronometer for calculating longitude at sea), actress Kay Kendall and the suffragist Eva Gore-Booth. Both graveyards have been designated Sites of Nature Conservation Importance and are managed as wildlife-friendly areas. Volunteers maintain the graveyards, which contain a wide variety of mature trees.
