Summarised from report:

The site of an Anti Aircraft Battery is visible on aerial photographs from the 1940’s, today little of the battery is visible but on the terrace on which it was situated is a rectangular depression, 14.0m long, up to 8.0m wide and 1.0m deep; the site of one of the Nissen huts. Remains of brick walls can be seen at both ends, 0.22m thick and surviving up to 0.8m high, both have entrances 0.9m wide. Although its function is unknown, the hut might have been a magazine, its sunken position providing some protection against blast and bombardment. There is no surface trace of the second Nissen hut, though its site is at the south western end of the complex. (1)
