Downtown is the largest business district in the city of Houston and the largest in the state of Texas, located near the geographic center of the metropolitan area at the confluence of Interstate 10, Interstate 45, and Interstate 69. The 1.84-square-mile (4.8 km2) district, enclosed by the aforementioned highways, contains the original townsite of Houston at the confluence of Buffalo Bayou and White Oak Bayou, a point known as Allen’s Landing. Downtown has been the city’s preeminent commercial district since its founding in 1836.

Today home to nine Fortune 500 corporations, Downtown contains 50 million square feet (4,600,000 m2) of office space and is the workplace of 150,000 employees. Downtown is also a major destination for entertainment and recreation. Nine major performing arts organizations are located within the 13,000-seat Theater District at prominent venues including Alley Theatre, Hobby Center for the Performing Arts, Jones Hall, and the Wortham Theater Center. Two major professional sports venues, Minute Maid Park and the Toyota Center, are home to the Houston Astros and Houston Rockets, respectively. Discovery Green, an urban park located on the east side of the district adjacent to the George R. Brown Convention Center, anchors the city’s convention district.
