A stone's throw east of Hampstead Heath, this beautiful cemetery is laid out around a huge 300-year-old cedar tree and is laced with serpentine pathways. The cemetery was so popular and fashionable in the Victorian era that it was extended on the other side of Swain's Lane in 1857. The most famous grave is that of Karl Marx, who died in Hampstead in 1883; his grave, marked by a gargantuan bust, is in the eastern cemetery. In the old western cemetery -- accessible only by guided tours, given hourly in summer -- are scientist Michael Faraday and poet Christina Rossetti.
