The TC Energy Center is a highrise representing one of the first significant examples of postmodern architecture construction in downtown Houston, Texas. Formerly known as the RepublicBank Center, the NCNB Center,the NationsBank Center, and the Bank of America Center, the building was completed in October 1983 and designed by award winning architect Johnson/Burgee Architects, and is reminiscent of the Dutch Gothic architecture of canal houses in The Netherlands. The building is connected to the underground system of tunnels, which lie 20 feet below Houston's downtown streets and are more than 6 miles long. Having started out years ago as a tunnel between two downtown movie theaters, today it includes restaurants, banks, salons, and service retail and connects 95 city blocks.
