I live in Lower Silesia, so not really close to the capital. I was told Warsaw has its metro stations in case the citizens there want to use them for cover, but I don’t know if my own area of living (Wrocław, Wałbrzych, Jelenia Góra) has that sort of “privilege” or “benefit”. I tried searching it up, but all I see are websites about Nazi shelters. Which are relics of the old times and therefore unusable.
