@jalefkowit reminds me of https://en.wikipedia.org/wiki/Bunkers_in_Albania "The bunkerisation programme was a massive drain on Albania's weak economy. [...] The programme diverted resources away from other forms of development, such as roads and residential buildings. On average, they are said to have each cost the equivalent of a two-room apartment and the resources used to build them could easily have resolved Albania's chronic shortage of housing."
