Preston Cleugh Fort is also known as Bunkle Edge Fort.
The monument is a later prehistoric fort, a defended settlement dating from the early to middle phases of the Iron Age (c.500-100BC). The interior of the fort is roughly oval in shape, with a flattened east side, and measures approximately 85 yards east-west by 70 yards north-south. On the northwest, west and south sides it is defended by three substantial ramparts with two medial ditches giving an overall height of over 10 feet in places. On the north and east of the fort, the steep natural defences of the site reduce the need for ramparts, with only the inner rampart continuing on the north and a separate section of rampart built to cover the east side. The main entrance to the site is from the west, but there is also a smaller entrance on the east. The footings of circular buildings have been recorded within the fort.
THE SITE IS BEST ACCESSED FROM THE SIGNPOST (BELOW) BUT IN SUMMER THIS GETS SO OVERGROWN SO AS TO BECOME NEAR IMPASSABLE. THE CACHE HOWEVER IS BEST ACCESSED BY PARKING AT THE WIDE FARM GATE AND WALKING THE SHORT WAY THROUGH THE WOODS. YOU DO NOT ACTUALLY NEED TO ACCESS PRESTON CLEUGH HILL FORT TO CLAIM THE CACHE BUT PLEASE DO AS IT IS BRILLIANT.
