One Market Plaza is a complex of three office buildings at 1 Market Street along the San Francisco Embarcadero. The historic 11-story Southern Pacific Building, also known as "The Landmark", was completed in 1916, and incorporated into the development in 1976 that includes the 43-storey 172 metres (564 feet) Spear Tower, and the 27-storey, 111 metres (364 feet) Steuart Tower. At over 1.5 billion pounds, the complex is considered the heaviest development in San Francisco.
