The Williams Tower (formerly the Transco Tower), is a skyscraper located in the Uptown District of Houston. It was designed by architects Philip Johnson and John Burgee, in association with Houston-based Morris-Aubry Architects, and erected in 1983. The tower is among Houston's most visible buildings and can be seen from as far away as Katy, Texas, a city located approximately 30 miles (48 km) west of Houston. The building is the 4th-tallest in Texas and the 23rd-tallest in the United States. When it was built, in 1983, it stood as the tallest skyscraper located outside a city's central business district.
