Royal Observer Corps Orlit Post

The Royal Observer Corps Orlit Post is an observation post used by the Royal Observer Corps during the Cold War to recognise enemy aircraft.

Experience from WW2 identified that there would be a need for increased protection from enemy aircraft if the UK was ever faced with the prospect of being at war again.

The idea for these new posts originated in 1947, however it was only during 1951/52 as part of the programme to update the air defences through the Rotor Plan that more substantial buildings were built to offer at least some level of protection from the elements or attack.

These Orlit structures were split into two sections.

The entrance door led into the smaller roofed section which was used as a shelter and store with a sliding door into the open section which housed the post instrument and chart on top of a wooden mounting.
