The Mob Museum (former US Post Office and Courthouse)

The Mob Museum, formally the National Museum of Organized Crime and Law Enforcement, occupies the former United States Post Office and Courthouse at 300 Stewart Avenue in downtown Las Vegas, Nevada. The Neoclassical building opened in 1933, during the Great Depression, and served as the city's main federal post office and courthouse for decades. Its second-floor courtroom became nationally significant in November 1950, when the Kefauver Committee, a Senate panel investigating organized crime in interstate commerce, held a televised hearing there, with testimony from figures connected to Nevada gambling. The building is listed on the National Register of Historic Places. After the federal government moved out, the city of Las Vegas acquired the structure, and it was renovated and opened as a museum in 2012. The collections cover the history of organized crime in the United States and the law enforcement response, with exhibits on Prohibition, the rise of Las Vegas casinos, famous investigations and the technology of surveillance and forensics. Named artifacts and spaces include the restored Kefauver courtroom, a section of brick wall from the Chicago garage associated with the 1929 St. Valentine's Day Massacre, and the museum's speakeasy and distillery in the basement. The curatorial approach is immersive and chronological, moving up through the floors with period film, interactive stations, firearms and personal objects. The Neoclassical character of the building, with its stone facade and formal interior, has been preserved while the galleries were fitted into the original rooms. Restoration work retained the courtroom details that matter to the Kefauver story, giving visitors a direct link between the exhibits and the place where the hearings occurred. The museum sits near Fremont Street and the Arts District, making it an easy anchor for a downtown history day.
