House of Terror
The headquarters of the dreaded ÁVH secret police houses the disturbing House of Terror, focusing on the crimes and atrocities of Hungary's fascist and Stalinist regimes in a permanent exhibition called Double Occupation. But the years after WWII leading up to the 1956 Uprising get the lion's share of the exhibition space (almost three-dozen spaces on three levels). The reconstructed prison cells in the basement and the Perpetrators' Gallery on the staircase, featuring photographs of the turncoats, spies and torturers, are chilling.
