About 101 California Street
101 California Street is a 48-storey office building completed in 1982 in the Financial District of San Francisco, California. The 183 m (600 ft) tower providing 1,200,000 sq ft (111,000 m) of office space is bounded by California-, Davis-, Front-, and Pine Streets near Market Street. The faceted cylindrical tower features a seven story, glass enclosed lobby and a granite plaza with flower beds and a fountain. The building's entrance is very similar to that of 101 Park Avenue in New York City, and was also designed by Philip Johnson and John Burgee in 1982. 101 California is equipped with a total of thirty-two elevators, with twenty-two serving the tower; two serving floors 45 through 48; four serving the triangular annex building; two serving the garage; and two for freight. The eight stairwells throughout the building are intended for emergency use only. The building is the site of what has become known as the 101 California Street shootings, a mass murder which occurred there in 1993. On July 1, Gian Luigi Ferri, a disgruntled client of the law firm Pettit & Martin, entered their offices on the 34th floor and killed eight people and wounded six before killing himself.
