Located on the corner of Fifth and Main Streets, it is noted for its Art Deco design with terracotta ornamentation and setbacks on the top floors.

The Blackstone Hotel guest list is full of notable people including Presidents of the United States: Harry S. Truman, Dwight D. Eisenhower, John F. Kennedy, Lyndon B. Johnson, and Richard M. Nixon.

The structure was built with reinforced concrete, and the exterior boasted buff color brick with terracotta ornament throughout.

The interior showcased a two-story lobby with a mezzanine, wide stairwells, a Venetian ballroom, and Italian marble placed on pillars and floors throughout.

[2] It was in the Blackstone's Venetian Ballroom that the Texas Democratic Executive Committee met in September 1948 to determine if Lyndon B. Johnson's narrow victory over Coke Stevenson was valid.

In the 1970s, the Venetian Ballroom served as a temporary pornographic cinema and Fort Worth police's vice squad made frequent arrests.

In 1979 Olympic gymnast Nadia Comaneci described her team's stay at the Blackstone as "awful, terrible, mediocre, but what the hell.

"[citation needed] The steady decline in business finally forced the closing of the hotel due to bankruptcy of the owners, seeing its last guest at that time in 1982.

Many windows in upper floors were broken or opened, allowing rain and birds to enter the structure, causing further deterioration.

There are no known original drawings of the interior, so HRI documented every aspect of the building, including measurements of floor-to-ceiling heights and mechanical equipment.

The guest room window frames, made of cypress wood, were restored, and broken glass replaced.

[4] The annex, originally constructed when the hotel was part of the Hilton chain in the 1950s, was converted to an indoor valet parking garage while the top floor hosted additional guestrooms, a swimming pool, hot tub, and a workout room.
