The Abandoned Warehouse is an old building in Beach City on the edge of a cliff near the ocean. It has been used for various purposes, including underground wrestling, rave parties and an improvised print shop for Bill Dewey's campaign.
It is a severely dilapidated brick building with a partially caved-in roof and some broken windows. The interior is a wide, open space, and one of the walls has almost completely collapsed.
It is located in an industrial area, a short walk away from Beach City, near a beach. In "Tiger Millionaire", the lighthouse and the Crystal Temple can be seen in the distance through the hole in the wall. This is north of the Crystal Temple, assuming the Crystal Temple faces east.
The warehouse is used as the venue for the Beach City Underground Wrestling tournament. During the tournament, the warehouse is set up with a single large ring located towards the back and several rows of folding chairs situated near the front facing the ring.
Sour Cream holds a rave in the warehouse attended by his internet friends, including Kevin. The warehouse features a dance floor, with lighting and sound equipment and a DJ table up on a raised platform.
It is shown that Mayor Dewey utilizes the warehouse on his campaign as a storage area. The warehouse contains a set of screen printing equipment, several cardboard boxes full of campaign materials, and campaign banners that are mounted on the walls.
During Amethyst's verse, the scene shifts from the Kindergarten to the warehouse. Amethyst lands on the wrestling ring, and a spotlight shines on her as she pulls out her whip.
Steven helps Sour Cream haul his DJ equipment to the warehouse. Marty, intending to promote Sour Cream, says he needs to be where the people are and decides that the rave be held on the beach instead.
