Over the years there have been several casinos and resorts planned for Las Vegas that never opened. The stages of planning may have been just an announcement or groundbreaking.
Where the Palazzo Casino and Resort currently stands (adjacent to the Venetian Hotel and Casino and the Sands Expo and Convention Center), an Asian themed casino was proposed but was rejected for the present Palazzo project.
Steve Wynn, who had purchased and demolished the Dunes, had originally planned to build a modern hotel in the middle of a man-made lake. He later built the Bellagio with a man-made lake in the front of the hotel. The name was later used by Wynn for a resort built in Biloxi, Mississippi.
In 1988, a sign for a proposed casino was erected on a fenced vacant lot on Flamingo Road. Standing near the sign was a scale model galleon. For several years, that was all that stood on the property. The empty lot was the source of many jokes by the locals until the ship, which was later damaged by a fire started by a homeless person, was torn down in the 1990s and the lot became the site of the Tuscany Suites and Casino co-owned by Charles Heers, the same man who has owned the property since the 1960s.
A proposed resort that was to have been built on the site of El Rancho Vegas. The parcel is now partially taken by the Hilton Grand Vacations Timeshares and Las Vegas Festival Grounds.
A San Francisco-themed resort was proposed for the site of the New Frontier Hotel and Casino. The project was rejected in favor of the Swiss-themed Montreux, which itself was canceled in favor of the Las Vegas Plaza, modeled after the Plaza Hotel in New York City. The project of the Las Vegas Plaza was also cancelled in 2011, due to the worsened economic conditions.
