Sheraton Dallas Hotel

The Sheraton Dallas Hotel, was built as the Southland Center in 1959. It is a three building complex in downtown Dallas. It is made up of the 42 story center tower, which is the 16th tallest structure in the city at 550 feet (168 m), the 31 floor north tower which is 448 feet (137 m) tall and the 28 story south tower which rises to a height of 352 feet (107 m). All three buildings are joined at the base to form one contiguous structure at street level. The south tower was completed first in 1959, as the Sheraton-Dallas Hotel. It was followed a year later by the center tower, which served as the headquarters of the Southland Life Insurance Company. The north tower was the final addition in 1981.

Southland Corporation vacated the complex when Cityplace Center was opened in 1988. The Sheraton tower closed soon after. The Adam's Mark hotel chain converted all three towers of the entire complex into one enormous hotel, the Adam's Mark Dallas, in 1998, in part due to the proximity of DART's light rail line and the adjacent Pearl Station.

When the Adam's Mark chain folded in 2008, the hotel rejoined the Sheraton chain.
