You are looking for a small cache located in a field near a partially destroyed agricultural building. The field can be accessed from the gate on the corner of Prospect Close and Gable Close, or from another gate near All Saints Church.
Please put the cache back in the exact place you found it and be careful of any livestock that may be present. Please note that, in order to find the cache, you do not need to cross the barbed wire fence that keeps livestock out of the building.
From the cache site you will have a nice view of All Saints Church at Compton Greenfield, as well as the surrounding countyside and hills. After finding this cache, you may want to cross the field and enjoy the multi cache at Compton Greenfield.
You will usually be able to find a place to park very close to the cache in Prospect Close or Gable Close, although please note that this is a residential area. There are also carparks at All Saints Church, at Easter Compton Village Hall and at a local Pub, all less than 1km away from the cache.
