Located on East Street Prittlewell, the Southend Borough Control was constructed in 1967 and was located in the basement of a Civil Defence Training Centre. The site closed only a year later when the Civil Defence was stood down.
The Bunker offered no blast protection but did provide fallout protection. Interestingly there are windows in the side of the building leading into the side of the control which would have been covered over in earth if the centre was needed. Another feature to note is that the backup generator is located in a separate surface-level building.
The site was used as a clinic until 1981 and now houses the local Royal Navy Association Club.
