Salesforce Tower (Indianapolis)

Salesforce Tower (formerly known as Bank One Tower, then Chase Tower, and originally conceived as American Fletcher Tower) is the tallest building in the U.S. state of Indiana. Opening in 1990, it surpassed the AUL Tower (now OneAmerica Tower) in Indianapolis for the distinction. The building's twin spires' are 811 feet (247 m) tall, while the 48 floors of office and retail space and 2 building equipment floors above that peak at the 701-foot (214 m) roof. It is the regional headquarters of Salesforce, which moved into the tower in the late-2010s and currently occupies a large amount of space in the building. While the tower has two spires of equal height, only one of them is functional as a transmission antenna. The other mast is merely an architectural decoration. The building was designed by KlingStubbins, and built by Indianapolis-based Huber Hunt & Nichols.

The tower's step pyramidal cap reflects the design of the Indiana War Memorial, three blocks due north. The War Memorial, in turn, reflects the descriptions of the original Mausoleum. Because of the height of this building, its roof was specifically designed to house communications relay equipment, in order to provide additional revenue to the building's owners. Over the past several years, two large banners have occasionally been placed outside the north and south communication bullpen areas of the roof in support of two of the city's professional sports franchises. These "Go Pacers" and "Go Colts" signs are highly visible being on the tallest structure in the city.
