ROC Newark is a Royal Observer Corps post in Nottinghamshire near Newark. It sits in a triangular compound surrounded by bushes on a field boundary away from the road close to a covered reservoir.
All surface features remain. The top of the entrance shaft has been rebuilt with larger hatch.
A padlock was fitted when the post was sold in 2003.
Royal Observer Corps (ROC) were given the responsibility of reporting nuclear bursts and monitoring fall-out. This was archived by the construction of underground monitoring posts throughout Great Britain and Northern Ireland. These were designed to give limited fall-out protection, usually at the same location as the aircraft monitoring post.
These posts are basic, with no mains electricity or running water. Toilet facilities were basic in the extreme consisting of a chemical toilet in a small room just off the main entrance. This entrance is a 15ft shaft, dropping down to a large monitoring room, approximately 15ft by 7ft in size. These bunkers were built to a standard design. The furniture was also standardised inside the bunkers. A ventilation shaft with two louvered vents was located alongside the entrance shaft with a second air shaft at the other end of the room. Lighting was provided by a 12 volt battery located behind the monitoring room door.
