The 320 South Boston Building, formerly known as the National Bank of Tulsa Building, is a 22-story highrise building located in downtown Tulsa, Oklahoma. It was originally constructed as a ten-story building in 1917, and expanded to its present dimensions in 1929. The addition brought the building's height to 400 feet (122 m), making it the tallest building in Oklahoma. It lost this distinction in 1931 but remained the tallest building in Tulsa until Fourth National Bank (today Bank of America Center) was completed in 1967.
Like the Empire State Building, the pinnacle of 320 South Boston was designed as a Zeppelin mooring. This was used at least once when a U.S. Navy Zeppelin moored there in the 1930s. The top of the building was also used for weather alerts, with flashing red lights in the event of a storm. The architect was George Winkler, who also designed the Mayo Hotel. #1917 #320_south_boston_building #art_deco #city #gothic #highrise #historic #navy #office_building #oklahoma #sardinas #skyscraper #tallest #tulsa #zeppelin
