It was the stage for the biggest Mob hearing in history.

Now it’s the setting for the nation’s most comprehensive Mob Museum. Located at 300 Stewart Avenue in the heart of downtown Las Vegas, The Mob Museum rests inside the historic former federal courthouse and U.S. Post Office. This building is one of the few remaining historically significant buildings in Las Vegas and is included on both the Nevada and National Registers of Historic Places and is also LEED Silver certified.

From 1950 to 1951, the Kefauver Committee hearings on organized crime were held in 14 cities around the United States. In Las Vegas, the hearings were conducted in the courtroom in this very building on November 15, 1950. The courtroom has been recreated to appear as it did back then, a true portal to a time when the Mob “ran the town.” As a visitor, get to experience this courtroom for yourself and be immersed in the story and courtroom where history was made.

On Nov. 15, 1950, the U.S. Senate Special Committee to Investigate Organized Crime in Interstate Commerce, led by U.S. Senator Estes Kefauver (Democrat-Tennessee), held the seventh in a series of 14 nationwide hearings in Las Vegas.  The historic hearing took place in the courtroom of the city’s first federal building – the very courtroom that was restored as the centerpiece of The Mob Museum, the National Museum of Organized Crime and Law Enforcement that opened on February 14, 2012.

The former federal courthouse and U.S. Post Office building is one of the few remaining historically significant structures in the city. Originally constructed under the U.S. Treasury Department’s Acting Supervising Architect James A. Wetmore, it is an important example of Depression-era neoclassical architecture built by the federal government during the 1920s and 1930s. The rehabilitation of the former federal courthouse restores the building to its original grandeur and preserves it as a cultural asset for generations to come. It features the historic restoration of the historic lobby, historic floor and the courtroom, famous as the site of the Kefauver Committee hearings, the series of hearings that marked the exposure of organized crime and the beginnings of federal prosecution in the early 1950s.
