Was just watching some documentary yesterday online about Poland/ Warsaw post-war Soviet era architecture. Massive multi-story apartment blocks with huge carved facings and towering feature piece solid concrete multi light lamposts ([MDM Housing Estate](https://architectuul.com/architecture/mdm-housing-estate). Huge multi hectare Civil administration/ university Palace building ([Palace of Science and Culture](https://thumbs.dreamstime.com/b/aerial-view-heart-downtown-palace-culture-science-middle-verticlal-warsaw-poland-aerial-view-115567060.jpg) - difficult to find a clear aerial shot for the true scale of the place, takes iirc 40 mins walk around the outside, has 3200 rooms.
