A large chunk of the TV series was based in a prison, they then moved on to the Alexandra Safe Zone, which was a gated type community in Virginia surrounded by walls, it looks like they have/are taking parts from both, the entrance and signs are from Alexandra (season 5-8) and the prison props and fence from that arc (season 3-5).
Personally, I wonder if Lucille is hidden somewhere in there as a prop.
