Norton Disney Maintenance Unit No.93 (also known as Swinderby) was a Forward Filing Depot. The site included two 250-ton underground mustard storage pots and facilities for filing weapons
In the post war period large quantities of chemical weapons were sent to Norton Disney for disposal and decanting prior to disposal. This continued well into the 1950s.
At one stage a planning application was lodged to turn the site into a children’s adventure/play site
Presently the land is of mixed usage for crops and scattered woodland
