Peachtree Center in the context of Metropolitan Atlanta Rapid Transit Authority

John Calvin Portman Jr. (December 4, 1924 – December 29, 2017) was an American neofuturistic architect and real estate developer widely known for popularizing hotels and office buildings with multi-storied interior atria. Portman also had a particularly large impact on the cityscape of his hometown of Atlanta, with the Peachtree Center complex serving as downtown's business and tourism anchor from the 1970s onward. The Peachtree Center area includes Portman-designed Hyatt, Westin, and Marriott hotels. Portman's plans typically dealt with primitives in the forms of symmetrical squares and circles.

A skyway, skybridge, skywalk, or sky walkway is an elevated type of pedway connecting two or more buildings in an urban area, or connecting elevated points within mountainous recreational zones. Urban skyways very often take the form of enclosed or covered footbridges that protect pedestrians from the weather. Open-top modern skyways in mountains now often have glass bottoms. Sometimes enclosed urban skywalks are made almost totally from glass, including ceilings, walls and floors. Also, some urban skyways function strictly as linear parks designed for walking.

In North America skyways are usually owned by businesses, and are therefore not public spaces as compared with sidewalks. However, in Asia, such as Bangkok's and Hong Kong's skywalks, they are built and owned separately by the city government, connecting between privately run rail stations or other transport with their own footbridges, and run many kilometers. Skyways usually connect on the first few floors above the ground-level floor, though they are sometimes much higher, as in the Petronas Towers. The space in the buildings connected by skyways is often devoted to retail business, so areas around the skyway may operate as a shopping mall. Non-commercial areas with closely associated buildings, such as university campuses, can often have skyways and/or tunnels connecting buildings.

The Westin Peachtree Plaza, Atlanta, is a skyscraper hotel on Peachtree Street in downtown Atlanta, Georgia, adjacent to the Peachtree Center complex and the former Davison's/Macy's flagship store with 1,073 rooms. At 723.0 ft (220.37 m) and 73 stories, a total building area of 1,196,240 sq ft (111,134 m) and a 187 ft (57 m) diameter, the tower was the tallest hotel in the world upon completion in 1976. Today, it is the fourth-tallest hotel in the Western Hemisphere, and the 28th tallest all-hotel building in the world.
