The Museum itself is contained entirely within a simple one-story building, ornamented with arches on one side of the facade and fitted with bars across the windows to prevent theft - for despite the faltering business, quite a few of the items inside are priceless artifacts. Situated somewhere in the deserts of Nevada, the Black Museum sits immediately adjacent to a lonely stretch of highway as with many such roadside attractions, the museum building is next-door to a gas station in order to encourage visits from curious travelers who've stopped to refuel, but by the beginning of the episode, the BRB station has long since been shut down, further whittling away at Haynes' potential customers. At present, the building serves as a part-time evil lair for Rolo Haynes - as well as a prison for the few artifacts unfortunate enough to possess a consciousness. Founded, owned and managed by Rolo Haynes, the building houses an extensive collection of authentic criminological artifacts from around the world, including items from past episodes of Black Mirror at some point prior to the start of this episode, the Museum once enjoyed record profits based on its lurid entertainment factor, but protests over the main exhibit ultimately drove away most of Haynes' customers, forcing him to make do with a much more unpleasant client base in order to keep his business open for the foreseeable future - if at all. The Black Museum is a roadside attraction appearing in the 2018 Black Mirror episode "Black Museum". There's a sad, sick story behind most everything here. Anything piques your interest, I can tell you all about it. Take a look around, take your time, see what pops out at you.
If it did something bad, chances are it's in here.
