Large bolt, approx 2 1/4" diameter on central leaded rib of Keep roof. Not sure any of the previous loggers have correctly identified it; it's certainly not the Environment Agency Bench Mark bolt a previous logger has photographed. Access is allowed to top of the Keep, on payment of 5.40 entrance fee to this English Heritage managed property, but signs warn not to go onto the leaded roof - on pain of prosecution!

Couldn't find it - could be inside the castle keep? Nice views of the old roman walls and the castle
