Fort Worth is the fifth-largest city in the U.S. state of Texas and the 13th-largest city in the United States. It is the county seat of Tarrant County, covering nearly 350 square miles (910 km2) into three other counties: Denton, Parker, and Wise. According to the 2019 census estimates, Fort Worth's population was 909,585. Fort Worth is the second-largest city in the Dallas–Fort Worth–Arlington metropolitan area, which is the fourth-most populous metropolitan area in the United States.
The city of Fort Worth was established in 1849 as an army outpost on a bluff overlooking the Trinity River. Fort Worth has historically been a center of the Texas Longhorn cattle trade. It still embraces its Western heritage and traditional architecture and design. USS Fort Worth (LCS-3) is the first ship of the United States Navy named after the city. Although considered by some to be a satellite city due to its proximity to Dallas, which has held a population majority since the 1950s, Fort Worth has become one of the fastest-growing cities in the United States in recent years, particularly in the 21st century, and has more than doubled its population in the last 30 years.
Fort Worth is home to the Van Cliburn International Piano Competition and several world-class museums designed by internationally known contemporary architects. The Kimbell Art Museum, considered to have one of the best art collections in Texas, is housed in what is widely regarded as one of the outstanding architectural achievements of the modern era.
