This is the bonus cache for the Ad Lab based on the Bunhill fields graveyard.
The name Bunhill evolved from Bone Hill established when over 1000 cart loads of bones were brought to the moor from St. Paul's Charnell House in 1549, deposited on the surface and covered with a thin layer of soil.
In 1665 it was used as a common burial ground for plague victims, and by 1746 it was marked on maps as "Tindal's Burying Ground", named after the owner of the land at that time.
As the ground was never consecrated by the CofE it has been used for burials by non-conformists and other non CofE denominations. In addition to the bones brought from St. Paul's there are over 120,000 interments in the graveyard including many famous persons, the lab stages will take you to the monuments for some of those, but some which aren't usually accessible include several members of Oliver Cromwell's family, steam engine pioneer Thomas Newcomen and Susanna Wesley (mother of Methodist minister John).
Complete the Lab cache and collect values for A, B, C & D from four of the stages, the fifth stage will give you a hint for the hide.
You will find the cache at : N51 31.ABC, W000 05.ADC
