One Seneca Tower is a skyscraper located in downtown Buffalo, New York. The building was formerly known as One HSBC Center (1999-2013), and prior to that, as Marine Midland Center (1972-1999), its name was changed in 1999 shortly after Marine Midland's parent company HSBC rebranded the bank as HSBC Bank USA. The building was constructed at a cost of $50 million between 1969 and 1972, and contains over 1,200,000 square feet (110,000 m²) of space. Today, the 40 story building still dominates the Buffalo skyline, at 529 feet (161 m), or 161.2 meters high. It is an example of modernist style architecture.
