I was never quite sure what these conical structures on the Tritonplatz were.
Cold war-era missile silos that weren't dug quite deep enough, exposing the nosecones to the elements?
(If this were to happen anywhere, then in Mainz..)
Oversized dunces caps from some carnivalistic celebrations?
OTT graffiti-approved areas?
Turns out that they're ultra-flash skylights for the rehearsal rooms at the Theatre.
How disappointingly normal...
