Atlas Obscura - odd places around the world. Has previously contained such high-octane weirdness as the Georgia Pyramid compound of Tama-Re.
Gamma World War (sample page: Japanese secret pyramid base)
I don't know much about Velvet Revolution yet except it lead me to the Prague Museum of Communism (relevant to my post-Soviet post-apocalyptic interests)
The Null Device, documenting interesting street art, Japanese War Tubas and similar sorts of things
Englishrussia is a gold mine of stupidweird. Here, "chechen" home-made firearms, also directly swipable for Tartary. Also some random nudity.
