Several Victorian cemeteries and pre-Victorian burial grounds still exist within central London. Almost all are free to access.
The cemeteries provide a glimpse into Victorian London and the churchyards are pleasant places to stop and rest, especially on warm summer days.

This burial ground was created for use in the Great Plague of 1665. However, it was not used for the burial of plague victims.
Instead it became the final resting place of non conformists - those who practised religions other than Church of England. John Bunyan, Daniel Defoe and William Blake are buried here.
It's a pleasant place to stop and rest and there are many cafes in nearby streets.

The area of Broadgate in the City of London marks the general vicinity of New Ground, London's first cemetery.
Established in 1569 on land belonging to the Bethlem Hospital, it was available to parishes who needed extra burial space, not only for plague victims, and continued to be used until 1720.
There's not much to see there these days as the site has been heavily developed.

Though the park opened in 1880, it was the seventeenth century burial ground for Christ Church, Newgate Street.
Since 1900 it has been a national memorial to heroic ordinary Londoners who died in acts of bravery.
Many Londoners continue to visit it, especially during their lunch breaks on sunny days.
