City National Plaza is a twin tower high-rise complex located in downtown Los Angeles
, comprising City National Tower and Paul Hastings Tower. The 213.1 m (699 ft) 52-storey structures are located on the site of the Art Deco Richfield Tower, that was designed by Morgan, Walls & Clements in the 1920s, and what is now the Paul Hastings Tower, became the new World
headquarters for the Atlantic Richfield Company (ARCO).
Upon completion in 1972, the towers of City National Plaza were the tallest buildings in the city for one year before being overtaken by Aon Center
, and were the tallest twin towers in the world until the completion of the World Trade Center in New York City.The towers are constructed of steel frames covered with polished panels of Forest
green granite and panes of bronze glass.
