That there is the ceiling of the lobby of the Guardian Building in downtown Detroit. The building is known as the "Cathedral of Finance" and the lobby is supposed to be cathedral-like, except honoring some kind of made up Aztec-y non-denominational art deco finance god. Leasing is now quite affordable.
In addition to the remarkable decor, the lobby features clean restrooms and the excellent Rowland Cafe, which I don't own and have never patronized. The cafe is named after Wirt C. Rowland, no relation, who also had a hand in designing Hill Auditorium here in Ann Arbor.
