The Lettie Pate Whitehead Evans Administration Building, commonly known as Tech Tower, is a historic building located at 225 North Avenue NW in Midtown Atlanta, Georgia, USA, and a focal point of the central campus of the Georgia Institute of Technology (Georgia Tech). Erected in 1888 and named the Academic Building, Tech Tower was one of the first two buildings to be completed on the Georgia Tech campus. Tech Tower was built as a venue for classroom instruction to complement the hands-on training taking place in the shop building beside it. Since the razing of the shop in 1892 following a disastrous fire, Tech Tower enjoys the distinction of being the oldest structure on the Georgia Tech campus.
