Concierge.com's insider take:
Located deep under Castle Hill in Buda, the Rock Hospital museum offers a glimpse deep into Budapest's World War II and Cold War past. Formed out of older, previously established tunnels and cellars in the rock, the Rock Hospital became an important part of the city's defenses during the American air raids of 1944 and treated wounded troops during the gruesome Siege of Buda the next year. In the Fifties—with the city a capital of the Communist bloc—the site was converted into a secret nuclear bunker in case of attack by Western forces. Today, tours in both Hungarian and English depart on the hour between 10 am and 6 pm. The circuit through former surgical theaters, recovery rooms, and air-filtration chambers (all protected by immense blast-proof walls and doors) takes about an hour. Due to its underground location, the hospital retains a temperature within the range of 59 to 64°F, making this a comfortable (and curious) attraction during the high heat of a Hungarian summer.—Evan Rail
