It's a building in Germany whose name translates into the "Palace of the Republic," and it served as the East German parliament building from the 1970s through the late 1980s. After the collapse of the East German state, performance and street artists took it over as squatters. I appreciate its retro architecture; it was something that stood out greatly in my travels. Sadly it has been demolished.
Interesting history: The main room contained hundreds of intricate light fixtures. This earned it the name Erich's Lampenladen, Erich's Store of Lightbulbs, after the then-authoritarian Communist Party General Secretary.
