US Bank Tower

US Bank Tower is a 310.3 m or 1,018 ft skyscraper at 633 West Fifth Street in downtown Los Angeles, California. It is also called as Library Tower and First Interstate Bank World Center. The details of U.S. Bank Tower are explained in world tour guides below. It is the tallest building in the state, the tenth-tallest building in the United States, the tallest west of the Mississippi River and as of December 2009 40th tallest building in the world.

US Bank TowerThe local building codes require the building to have a helipad it is also the tallest building in the world with a roof top heliport. Until the construction of Taipei 101 it was also the tallest building in a major active seismic region; its structure was designed to resist an earthquake of 8.3 on the Richter scale. It consists of 73 stories above ground and two parking levels below ground.

The Construction of U.S. Bank Tower began in 1987 with completion in 1989. The building was designed by Henry N. Cobb of the architectural firm Pei Cobb Freed & Partners and cost $350 million to build. It is one of the most recognizable buildings in Los Angeles often used in establishing shots for the city in films and television programs.

The building is also known as Library Tower because it was built as part of the $1 billion Los Angeles Central Library redevelopment area following two disastrous fires in 1986 and its location across the street. The City of Los Angeles sold air rights to the developers of the tower to help pay for the reconstruction of the library. The building was also known for a time as First Interstate Bank World Center but the name Library Tower was restored after First Interstate Bancorp merged with Wells Fargo Bank. In March 2003 the property was leased by U.S. Bancorp and the building was renamed U.S. Bank Tower.

The crown is lighted with red and green during the Christmas holiday season and lit red around Saint Valentine's Day. It is also lit with purple and gold when the Los Angeles Lakers are playing in the NBA Playoffs and blue and white on Opening Day for the Los Angeles Dodgers and when the Dodgers are playing in the playoffs. The crown was also lit with red, white and blue during the July 4 holidays, but that practice ended in 2003.

On February 28, 2004, two 23 m or 75 ft U.S. Bank logo signs were installed on the crown amid controversy for their effect on the aesthetic appearance of the building much like previous First Interstate Bank logos were placed on the crown between 1990 and 1998. First Interstate Banks I logo on crown was in the 1993 Guinness Book of World Records for highest placed logo. On June 16, 2004, the 9/11 Commission reported that the original plan for the September 11 attacks called for the hijacking of ten planes, one of which was to be crashed into the building.
