The Mob Museum

The Mob Museum — formally the National Museum of Organized Crime and Law Enforcement — occupies a restored 1933 federal courthouse a five-minute walk north of Fremont Street. It isn't a themed attraction wearing a history costume: the second-floor courtroom is the actual room where the Kefauver Committee held its Las Vegas organized-crime hearing in 1950, and the galleries around it are built on real evidence — murder weapons, wiretap rigs and case files from the agents who spent decades taking the syndicates apart.

Three exhibit floors run chronologically from the top down — Prohibition and the birth of the syndicates on 3, the Kefauver era and the Vegas casino skim on 2, present-day organized crime on 1 — and the basement holds The Underground, a speakeasy that distills its own moonshine on site. Two honest caveats: this is a reading-heavy museum, so a proper visit takes two to three hours, and the marquee interactives — Crime Lab, Use of Force and the Firearm Training Simulator — are ticketed on top of general admission, which pushes the cost of a full visit well past the headline rate. If that stings, the core galleries alone still justify the trip Downtown.
