Chesterton Methodist Church's current building dates from 1965, and is an unusual octagonal design with a green roof. The church previously met in a more traditional building in the High Street a few hundred yards away. The church is a daughter church of Wesley Methodist in the city centre and part of the Cambridge Wesleyan circuit.
The cache is a disguised nano. The squeamish and keen gardeners attempt it at their own risk. I would recommend tweezers or something similar to get the log out.
Congratulations to Railwayfan for the FTF
