With a commanding presence in the city skyline, the 73-story Westin Peachtree Plaza is situated in the heart of downtown. The hotel is attached to AmericasMart and just a short walk from the Georgia Aquarium, the Georgia Dome, and the World Congress Center. The dark steel and glass tower was designed in 1976 by John Portman, and still stands as the tallest hotel in the Western Hemisphere. Portman's contemporary design for the Westin incorporates four floor-to-ceiling window panels in each of the 1068 guestrooms and suites (over 6300 windows total). Sweeping views are also perks at the 9th floor pool, which has retractable roof, as well as the revolving, top-floor restaurant, Sun Dial.
