The Glenn Building dates back to 1923, when it was built for office space. Named after the mayor of Atlanta at the time, John T. Glenn, the building was constructed following the installation of the Spring Street viaduct. The Glenn was built to be part of a larger complex of office buildings; however the other buildings in the complex were never completed and The Glenn building stood vacant for years. In the early 1980s, the Glenn building was bought by the Federal Reserve Bank. Later Philips Arena purchased the building from the Federal Reserve Bank and sold it to Legacy Properties.
