text: It is demolished but not entirely. Foundations and lower parts of walls remain. It is too contemporaneous to be considered as a "ruin" in my opinion. Nonetheless, the demolished OPs have clearly visible remains and traces and are very much mapable on that basis.
  
  The Dartmoor ranges are open to the public outside of scheduled live firing times. Firing consists of small arms and simulators only since the use of mortars, grenades and AT weapons was ceased to preserve the environment, and the marshals police the exercise areas after firing to ensure nothing remains. Occasionally one will find the odd empty 5.56mm case on the ground or traces of the dye from grenade simulators but otherwise it is quite safe to explore when open. Many, many people, myself included, spend many, many pleasant hours hiking over the ranges.
