This 1984 photo shows the view looking to the west from the roof of the Equitable building. In the center of the photo is the Centennial Tower at 101 Marietta Street NW. When it opened in 1975, it was known as the 101 Marietta Tower and following a 1998 renovation it was renamed Centennial Tower. Google map
