Ceausescu's Bunker, Bucharest

This bunker, located in Bucharest, Romania, was built for the country's late communist dictator Nicolae Ceausescu. The hermetically-sealed heavy steel door to the bunker opens with a squeak, releasing a burst of cool air. The bunker offers a window into Romania's communist past under Ceausescu's rule. Romania was also occupied by Soviet forces from 1944 to August 1958, during which the Soviet Union maintained a significant military presence in the country.
