... that the mediaeval Castle Knob in Derbyshire, England, was the site of a Cold War nuclear monitoring station?
Source: Date of foundation is unknown but likely 12th century and certainly before 14th century: "there is no documentary record for this site before the fourteenth century, and the date of construction is unknown. Nevertheless, from the present remains it appears to have been a motte-and-bailey construction and would be consistent with those constructed during King Stephen's reign" from: Boston, Hannah (2024). Lordship and Locality in the Long Twelfth Century. Boydell & Brewer. p. 82. ISBN978-1-78327-783-4. and " Excluded from the scheduling are all perimeter fencing, the sheds and stable within the area of the north bailey, and the underground MOD installation in the central bailey although the ground beneath all these features except the MOD installation is included." from: "Castle Gresley motte and bailey castle, Castle Gresley - 1011209". Historic England. Retrieved 18 October 2024.; the plaque on the site makes it clear this is a Royal Observer Corps monitoring post
ALT1: ... that a settlement in Derbyshire, England, is named after a Knob? Source: "The Gresleys, more unusually, seem to have built a castle at their caput. The name is preserved in the current name of Castle Gresley, and in a mound, still approximately 20 feet high, known locally as Castle Knob, that lies about a mile from the remains of Gresley Priory" from: Boston, Hannah (2024).
