Holbeach Royal Observer Corps Underground Monitoring Post

The Heritage Trust of Lincolnshire was offered an intact bunker near Holbeach in south Lincolnshire and agreed to take it in order to preserve it for future generations. In 1955, the government of the day reformed the Royal Observer Corps (ROC) who had been stood down after the war. Their WWII job had been to spot and identify incoming enemy aircraft. Their new job was to staff nuclear bomb monitoring posts. At first these monitoring posts were above ground but, in time, underground rooms were constructed.

Three ROC members would have staffed an underground monitoring post. They would have gone there if the threat of nuclear attack had become significant. Their task was to take measurements of the scale of the nuclear bomb blast and its resultant fallout over a period of up to three weeks after the attack. This information was telephoned or radioed back to a regional headquarters on a routine basis and went on to a national centre in order that the location and extent of blast and fallout nationally could be managed. Holbeach Bunker is situated off Washway Road, Holbeach.

opening times

The bunker is open to the public on a number of occasions throughout the year such as during the annual Heritage Open Days in September.
