The cache is hidden in the fork of one of the row of large chestnut trees on the western side of this fine London park.
Brief History (Part 1):
Clissold Park is a designated 56 acre community park with with children's playgrounds., sports fields, a bowling green, tennis courts, cafe and 
some other attractions including terrapins in its lakes. It also comprises remains of the New River and some Capital Ring paths run though the park.
The villa, Clissold House (formerly Paradise House) was built in the 1790s, for Jonathan Hoare, a City merchant, Quaker, philanthopist and anti-slavery campaigner. It was created to be his idyll and the stretch of water which wends its way around the house was once part of the New River, a canal that supplied London with clean water from Herfordshire - other remnants of the New River can be seen in Canonbury. It is a now a Grade II listed building . .
