Range Marker?

Part embedded into one of the main forest trackways, near Gorely Bushes, are the square to rectangular remains of a concrete and brick building. Nearby, adjacent to the track, is a displaced shuttered concrete footing, possibly for a large post, judging by the square void in it. The concrete components of both these features appear, by nature and matrix, to be of Second World War period. The track runs through Island Thorns and Amberwood Enclosures from Fritham, through Ashley Cross and the old World War Two ranges to Godshill Ridge. I would suggest that these features relate to the wartime uses of the area and represent a guard house or range gate. It's staggering how much of the forest was utilized during the war
