The Landmark was a hotel and casino located in Paradise, Nevada, east of the Las Vegas Strip and across from the Las Vegas Convention Center.
The resort included a 31-floor tower, inspired by the design of the Space Needle tower in Seattle.
Frank Caroll, the project's original owner, purchased the property in 1961.
Fremont Construction began work on the tower that September, while Caroll opened the adjacent Landmark Plaza shopping center and Landmark Apartments by the end of the year.
The tower's completion was expected for early 1963, but because of a lack of financing, construction was stopped in 1962, with the resort approximately 80 percent complete.
Up to 1969, the topped-off tower was the tallest building in Nevada until the completion of the International Hotel across the street.
In 1966, the Central Teamsters Pension Fund provided a $5.5 million construction loan to finish the project, with ownership transferred to a group of investors that included Caroll and his wife.
The Landmark's completion and opening was delayed several more times.
In April 1968, Caroll withdrew his request for a gaming license after he was charged with assault and battery against the project's interior designer. Billionaire Howard Hughes, through Hughes Tool Company, purchased the Landmark in 1969 at a cost of $17.3 million.
Hughes spent approximately $3 million to add his own touches to the resort before opening it on July 1, 1969, with 400 slot machines and 503 hotel rooms.
In addition to a 14,000 sq ft (1,300 m) ground-floor casino, the resort also had a second, smaller casino on the 29th floor; it was the first high-rise casino in Nevada.
Aside from the second casino, the five-story cupola dome at the top of the tower also featured restaurants, lounges, and a night club.
