Aon Center is a 62-story, 860 ft (260 m) Modernist office skyscraper at 707 Wilshire Boulevard in downtown Los Angeles, California.Site excavation started in late 1970, and the tower was completed in 1973. Designed by Charles Luckman, the rectangular bronze-clad building with white trim is remarkably slender for a skyscraper in a seismically active area.
