Dome

Round, circular skywalk that links the tower with neighboring buildings spanning Smith Street, above the traffic; 1500 Louisiana Street, formerly Enron Center South, is 600 ft (183m) tall and has 40 floors. It is the 17th tallest building in the city. Enron, a Houston-based company, had the building constructed to serve as its US headquarters. Due to a scandal in late 2001 the company collapsed and filed for bankruptcy that same year; Enron never occupied the building. It is now owned by ChevronTexaco. The building has multiple components; a large glass tower, a building block with white facade at the base, a cylindrical entry rotunda in glass and a round, circular skywalk that links the tower with neighboring buildings spanning Smith Street, above the traffic.
