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 at the corner of Third Street and Boston Avenue as a ten-story headquarters building for the Exchange National Bank of Tulsa, Oklahoma in 1917, and expanded to its present dimensions in 1929.[1][2] The addition brought the building's height to 400 feet (122 m), making it the tallest building in Oklahoma.[1] 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. It is now included in the Oil Capital Historic District.
The building sits on the west side of Boston Avenue and extends a full city block between Third and Fourth Streets. The architectural style is Beaux Arts. It is covered in brick with terra cotta trim. The lower two stories are covered in terra cotta. The central tower is stepped at the 20th floor, with a two story arcade section, which is topped by a temple fronted section. A cupola tops the section.[3] For many years, the cupola was illuminated by floodlights whose color changed according to the latest weather forecast. Green light meant a fair weather forecast, while red lights signified an approaching storm.[lower-alpha 1]
In 1933, Exchange National Bank reorganized and renamed itself as the National Bank of Tulsa. Thereafter, the building was known as the National Bank of Tulsa Building (or NBT Building), until the bank renamed itself as Bank of Oklahoma (BOK). The BOK moved to its newly constructed BOK Tower in 1977. The NBT Building reverted to its former 320 South Boston Building name and became a general office building. Among the tenants are Hall Estill, one of Oklahoma's largest law firms.
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 illuminated for weather alerts, with flashing red lights in the event of an approaching storm.[5][6]
The architect was George Winkler, who also designed the Mayo Hotel.[1]
