The San Francisco Marriott Marquis is a 133 m (436 ft) 39-story skyscraper in the Financial District of San Francisco, California. Situated at the intersection of Fourth and Mission Streets, across from the Metreon and Moscone Convention Center, the building is recognizable by the distinctive postmodern appearance of its high-rise tower. The building was completed in 1989, and contains 1,500 hotel rooms. The original architectural firm Zeidler Partnership Architects was replaced by DMJM architect Anthony J Lumsden, who gave the building its overall architectural style.
