Anti tank blocks. 10/1996 Two lines of anti-tank blocks and a pillbox have been identified from a vertical aerial photograph (RAF 1066/Scot/UK/64, 4024, flown 1946). Two lines of anti-tank blocks in a chevron pattern can be seen immediately to the N of the central bend, running down to the Allt a Choire Sheiridh.
The pillbox has been separated from the anti-tank blocks by the road improvement at this point, the two lines of anti-tank blocks survive, though those at the W (new road) end of the group have been reduced to small mounds of concrete. Construction of the anti-tank blocks has the appearance of layered blocks; they are also somewhat taller than those seen elsewhere. A 1950s photograph of the Devils Elbow and the anti-tank blocks can be viewed in the Glen Shee ski lodge to the N.
