First Tennessee Plaza

The First Tennessee Plaza, or Plaza Tower, is an office high-rise located at 800 Gay Street in Knoxville, Tennessee, USA. Completed in 1978, the 27-story structure is Knoxville's tallest building and an iconic part of the city's skyline. The building was originally known as the United American Plaza, with its current name being adopted in 1995 to reflect its anchor tenant, First Tennessee.
