If you’re looking for interesting Tumblr accounts to follow, boy do I know of a humdinger. It’s called “Architecture of Doom.”
From its FAQ page (film hyperlink courtesy of me):
The idea of the blog was to post mostly architecture that is often seen as bleak/gloomy/forbidding/desolate/unfortunate and totalitarian architecture. The name comes from a documentary with that name (Undergångens arkitektur is the original title in Swedish) about the Nazi aesthetic.
Below are some images culled from its pages.
