Atlanta architect and developer John Portman transformed the downtown Atlanta skyline and contributed to the revitalization of the inner city beginning with construction of the Merchandise Mart in 1961.
When the Hyatt Regency Atlanta opened in May 1967, Portman’s $18 million, 800-room hotel was hailed by architectural critics. Within three months of opening, the hotel booked a spectacularly successful ninety–percent occupancy rate. The open-atrium design influenced hotel architecture worldwide and the Hyatt Corporation adopted the design feature as a company standard with twenty-six open-atrium hotels by 1987.
"Portman’s buildings radically changed the skyline, modernizing it and defining Atlanta’s look for its late-20th-century ‘world class’ era."
