History reveals the great city of Babylon was conquered in one night, without resistance, in 539 BC by Cyrus the Great. Revelation 14:8 reads:
14:8 And there followed another Angel, saying, Babylon is fallen, is fallen, that great citie, because she made all nations drink of the wine of the wrath of her fornication.
It says “city”. So I’ve always thought it might be NY City or maybe LA ( Hollywood). It talks about sexual sin being the thing that causes it to get destroyed so that would make me think of LA more than NY.
How about Washington DC?
