1400 Smith Street

1400 Smith Street is a 691 ft tall skyscraper located in downtown Houston, Texas, United States. The building has 50 floors and is the 11th tallest building in the city. Designed by architectural firm Lloyd Jones Brewer and Associates, the building was completed in 1983. The 1,200,000-square-foot office tower is situated on Houston's six-mile pedestrian and retail tunnel system that links many of the city's downtown towers. It was formerly Four Allen Center, a part of the Allen Center complex.
The building was the former headquarters of Enron, one of America's largest commodities trading companies during the 1990s and later infamous for its financial scandal in 2001. 1400 Smith Street was originally known as Four Allen Center prior to Enron relocating to Houston in 1985. Before Enron's collapse, the energy giant constructed a second, similar building across the street, connected to 1400 Smith Street by a circular skywalk.
