As you make your way to this cache you will pass Moosey's Trail 13.
You are looking for a small sized camouflaged cylindrical container.
Aldenham was mentioned in the Doomsday book and remains unspoilt and largely unchanged since Saxon times when the majority of the land was owned by the Abbots of Westminster Abbey. The Church of St John the Baptist is 700 years old and there is good reason to believe that an earlier Saxon church stood on the site. Complete rebuilding took place around 1250 and substantial portions of this structure can still be seen. Close to the church stand a number of buildings of historical interest. The earliest of these is Aldenham Social Club - a late medieval hall house dating from around 1500. To the west of the churchyard stands Church Farm House (16th - 18th century) and to the east the old vicarage (now two dwellings), is a fine example of early 18th century red brick architecture.
