Dallas is the third-largest city in the U.S. state of Texas. It is the largest city in the Dallas-Fort Worth metroplex, the fourth-largest metropolitan area in the United States, with a population of 8.3 million as of 2024. Dallas is the site of 85 completed high-rise buildings over 300 feet (91 m), 20 of which stand taller than 492Â ft (150Â m). Dallas' skyline is one of the largest in the Southern United States. It has the second most skyscrapers taller than 492 ft (150 m) in Texas, after Houston. The tallest building is the Bank of America Plaza, which rises 921Â ft (281Â m) in Downtown Dallas and was completed in 1985.
The history of skyscrapers in the city began with the 14-story Praetorian Building in 1909, often regarded the first in Dallas or even the entire Western United States. The 1920s saw the construction of notable office towers such as the Davis Building, Santa Fe Building, and the Magnolia Building. While Dallas' skyline was mostly unchaged during the Great Depression and World War II, the Mercantile National Bank Building was the only major office building completed during the war. Built in 1943, it was the tallest building completed during World War II. After the war, Dallas resumed high-rise construction earlier than most U.S cities. Gables Republic Tower, completed in 1958, was the first building to surpass 492 ft (150 m) in Dallas. From the mid-1950s to 1970s, the city's skyline grew steadily under a skyscraper boom downtown. Dallas' current second-tallest building, Renaissance Tower, was built during this period to a height of 710 ft (216 m). Its height was later increased to 886 ft (270 m) in 1986.
