1. Golden Nugget Casino
The largest casino in downtown Vegas is the Golden Nugget. Covering over 38,000 square feet, it was initially built in 1946 and has been renovated over the years, adding into a new Las Vegas hotel tower. The casino earns its name "Golden Nugget" because the world's largest nugget of gold, 27.21kg, is located in the hotel's lobby. The Nugget originally was found in the 1980s and then later sold to this casino.
