Redoubt, Main Road, Harwich, Essex
After 1910, the Harwich Redoubt became barrack accommodation and from the 1920s the site was unused and falling into disrepair. It was taken back into military use during the second world war and, after the war, was transferred to the Civil Defence, who used the fort for atomic exercises until their disbandment. The redoubt is suffering the effect of leaks with significant loss to the inner and outer moat walls. Internally there are clear signs of plant growth throughout due to failing roof coverings
