Aon Center is a 62-story, 858 ft (262 m) Modernist office skyscraper at 707 Wilshire Boulevard in downtown Los Angeles, California.

Designed by Charles Luckman, the rectangular bronze-clad building with white trim is remarkably slender for a skyscraper in a seismically active area.

Aon Center was originally named the United California Bank Building from its completion in 1973 until 1981, when it became First Interstate Tower.

Shorenstein, which purchased the Aon Center in 2014, sold the building to a consortium of investors including Carolwood in December 2023.

[8] The fire was so severe because the building was not equipped with a sprinkler system, which was not required for office towers at the time of its construction.
