The First Interstate World Center exists today for one reason: its neighbor, the Los Angeles Central Library, found itself in deep trouble. Ravaged by fire in 1986, the library was one step away from the wrecking ball when an urban development team stepped in. The team bought the ailing structure, restoring the library and building a 75-story skyscraper adjacent to it.
Originally called the Library Tower, the name soon changed when First Interstate Bancorp negotiated to occupy a portion of the building in 1990 in exchange for having it renamed. Just six years later, the skyscraper reverted to its former name when First Interstate Bancorp was taken over by another local bank.
Located just 26 miles from the San Andreas Fault, the skyscraper was built to withstand the "Big One," an earthquake the magnitude of 8.3 or bigger on the Richter scale. The skyscraper's massively reinforced central core and lighter perimeter columns form a framework flexible enough to resist violent side-to-side shaking, but stiff enough to resist the enormous wind forces that affect high-rise buildings.
Here's how this skyscraper stacks up against the biggest skyscrapers in the world.
