#22, Vatican City
They do let lapsed Catholics into the Vatican, by the way. No press pass required. While I don't usually include Roman numerals in my number hunting, if there's one place where such a thing makes sense, it's Roma. But there's more to love about XXII than the way it looks. There's the brilliant dark comedy Catch-22 by Joseph Heller. There's the haunting song "22" by Richard Buckner. And then there's Twenty-two, the creepy Twilight Zone episode (is there any other kind?) where 22 stands in as the room number of the hospital morgue.
