From the Wikipedia page [1]
Highgate Cemetery is a place of burial in north London, England. It is designated Grade I on the English Heritage Register of Parks and Gardens of Special Historic Interest in England. It is divided into two parts, named the East and West cemetery. There are approximately 170,000 people buried in around 53,000 graves at Highgate Cemetery. Highgate Cemetery is notable both for some of the people buried there as well as for its de facto status as a nature reserve.
The cemetery in its original form – the northwestern wooded area – opened in 1839, as part of a plan to provide seven large, modern cemeteries, known as the "Magnificent Seven", around the outside of London.
The Friends of Highgate Cemetery Trust was set up in 1975 and acquired the freehold of both East and West Cemeteries by 1981, since when they have had responsibility for the maintenance of the location. In 1984 they published Highgate Cemetery: Victorian Valhalla by John Gay.
