Also having grown up in Denmark in the late 80's, I definitely had some of the same experiences; my school was built in the late 30's/early 40's, so not built for the cold war (but was reportedly used as the local Nazi HQ during WW2). But I can definitely recognize that a lot of 60's and 70's architecture was dual-purpose. Kulturministeriet (The Danish agency for Culture and Palaces) has a great section on the Cold War ("Kold Krig" in Danish) at https://slks.dk/omraader/kulturarv/bevaringsvaerdige-bygninger-og-miljoeer/bevaringstemaer/kold-krig/ https://slks.dk/omraader/kulturarv/bevaringsvaerdige-bygning....

There'a also a book, Kold Krig, which is available as a PDF at https://slks.dk/fileadmin/publikationer/Kulturarv/Kold_Krig_2014.pdf https://slks.dk/fileadmin/publikationer/Kulturarv/Kold_Krig_... (but I can't make Google translate ... translate) And I still have to visit www.reganvest.dk some day :)
