Bank of America Building Bank of America Building (also known as the library building and the first interstate world center) is located at 633 West Fifth Street in downtown Los Angeles, California, USA. It is the tallest skyscraper in North America west of Chicago and the tallest building in California. In addition, the u.s. bank tower is also the tallest building, with a helicopter airport on the top floor (built according to the building law of Los Angeles). With a height of 10 18 feet (3 10 meter), the Bank of America Building is one of the tallest skyscrapers in the world (ranked 22nd in 2005). Before the completion of Taipei 10 1, the Bank of America Building was also the tallest building in the main seismic activity area, and the building itself was designed to withstand an earthquake with a magnitude of 8.3 on the Richter scale. The Bank of America Building is 73 stories high and has two underground parking lots. It was designed by I.M. Pei's architect Henrey N. Cobb, with a total cost of $350 million.

This building is also called the "Library Building" because it is located across the street from the Los Angeles Central Library. 1986, after two disastrous fires, Los Angeles allocated 1 billion dollars for reconstruction, part of which was used to renovate the Los Angeles Central Library. The city of Los Angeles also sold the airspace right to the builder of the Federal Bank Building to supplement the whole construction plan of the library. The Federal Bank Building was once called the "First Interstate World Center" because it was acquired by the First Interstate Bank. Later, due to the merger of Bank of China and Wells Fargo, the name of the library building was mentioned again. In March 2003, the building was acquired by Bank of America Group, so it was renamed the Federal Bank Building. However, people in Los Angeles are still used to calling this building the library building.

The part of the building with a large glass design at the top is called the "crown", and it can be seen to glow at night. On the 4th of July, this "crown" will be lit by red and blue lights, and if it is during Christmas, it will be lit by red and green lights. When the Los Angeles Lakers play the NBA playoffs, the "crown" will be lit with purple and gold (these two colors are the representative colors of the Lakers). On February 28th, 2004, Crown was hung with two billboards bearing the trademark of Bank of America, each of which was 75 feet (23 meters) high, which was considered to destroy the aesthetic feeling of the building itself and caused serious controversy. (1990 to 1997, when the first interstate bank put the trademark billboard on the crown, it also caused the same controversy. )
