There are several areas in Czech republic where you can still find the remnants of military presence. At our vacation we were staying in a camp neaar Ralsko. The whole area is an ex-russian military operation and bases site, mixed with uranium mines. All around you can also find concrete bunkers, which were part of our defenses during the WW II. The picture below is of a hidden hangar at Hradcany airport. The size of the airport is pretty impressive even by today standards. If you are ever in the area, I definatelly recommend a visit. Some of these hangard are also accessible through the exhaust tunnels, but sometimes inhabbited by hobos :D. You could also see the inside (along with hobo furniture) in Jana’s recent post Hangar.
