Sparta Junior is a small gay sex cinema on the Seilerstraße in St. Pauli, just off the Reeperbahn. Behind the screening room there is a sling, a darkroom and a play area, and the house runs naked nights where clothes come off at the door.
It is part of the Sparta group of sex shops and cinemas on the Kiez, and works as a straightforward gay cruising and meeting spot rather than anything polished.
