Union Bank Plaza is a Los Angeles Historic-Cultural Monument listed 40-story, 157m (515feet) office skyscraper located on South Figueroa Street in Downtown Los Angeles, California.
Designed collaboratively by Harrison & Abramovitz and A.C. Martin & Associates, construction of the building began in 1965 and was completed in 1968 for the Connecticut General Life Insurance Company. It was the first skyscraper built in the central business district of Los Angeles as part of the Bunker Hill redevelopment project following the repeal of limitations on construction greater than 150 feet in height in 1957. Noted landscape architect Garrett Eckbo designed the three-acre modernist outdoor plaza on top of the parking garage.[2]
The property was named for the formerly Los Angeles based Union Bank & Trust Company, who leased 14 floors for their corporate headquarters. Having gone through a number of mergers and acquisitions over the years, successive owners have maintained the brand and retained the naming rights for their west coast offices, however Union Bank's December 2022 merger with U.S. Bancorp has resulted into folding the Union Bank name into the U.S. Bank brand, who also leases the U.S. Bank Tower for their Los Angeles offices, so the future of the naming rights are currently uncertain. Union Bank Plaza was also acquired by Waterbridge Capital for roughly $110,000,000 in March 2023.[3]
Currently the 22nd tallest building in Los Angeles, the complex was named a Los Angeles Historic Cultural Monument in 2020, the first skyscraper in Los Angeles to earn that distinction.[2]
