From afar, this looks like another monument in a city full of them, and in a way, it does commemorate the Cold War era very effectively. It’s the entrance to a massive underground bunker designed to house Communist Party elite in case of nuclear attack. Appropriately enough, it’s shaped like a big button. The rest of the city? Not quite, “Let them eat cake,” but almost. In contrast to the first metro line (now called the Millennium Underground, as it was built in time to celebrate Hungary’s first millennium in 1896), which is literally right under Andrássy út, the second and third lines are deeper underground, and its stations were the designated fallout shelters for the general population.
Having now seen this vs. the metro stops, well, it’s good to be
king general secretary.
