Aerial Defences of the Clyde

This project, which was largely undertaken in 2017, identified military sites which were constructed to protect the River Clyde from enemy aerial attack, with the earliest dating to World War One and the latest to World War Two. A total of just over 500 sites, including light and heavy anti-aircraft batteries, rocket launching and searchlight positions, barrage balloon anchorages, decoy sites and mine-watchers’ huts have been identified, mainly from contemporary records, including aerial photographs. Over 400 of the sites added to the NRHE were previously unrecorded.
