18. Highgate Cemetry, London
Highgate Cemetery has some of the finest funerary architecture in the country and is the resting place of many notable individuals including the novelist George Eliot, the poet Christina Rossetti and of course Karl Marx. If stories are to be believed it is also home to many weird goings on. During the 1960s there were reports of sinister cults carrying out strange rituals in the grounds at night. Witnesses have claimed to have seen a ghostly cyclist, and an old woman racing between the graves searching for the children she allegedly murdered.
