Moscone Center, Convention center in South of Market, San Francisco, United States

Moscone Center is a convention complex of three halls across three blocks in South of Market: Moscone South south of Howard Street, Moscone North north of it, and Moscone West across 4th Street. North and South are linked by a pedestrian bridge over Howard Street and by an underground exhibition hall that runs beneath Yerba Buena Gardens. The photograph shows the flat roof carried on white V-shaped columns, the "MOSCONE CENTER" lettering on the canopy and a row of flagpoles along the street.

Construction began in 1978 on South of Market land claimed by the San Francisco Redevelopment Agency, after low-income residents fought displacement through the 1960s and 1970s. George Moscone had opposed the project as a supervisor, but as mayor convened a committee of supporters and opponents, and a compromise he backed passed overwhelmingly in November 1976. The first hall, designed by Hellmuth, Obata & Kassabaum under Bill Valentine, opened in 1981 with its exhibition space placed underground to reduce its visible footprint.

The center's name honors George Moscone, the mayor assassinated in November 1978, though as a supervisor in the 1960s he had opposed the project over the displacement of elderly and poor residents. Apple held its WWDC developers conference at Moscone West every year until 2016. The complex appeared in the 1995 film The Net with Sandra Bullock.

Moscone North and South are joined by a pedestrian bridge over Howard Street and by an underground exhibition hall that runs beneath Yerba Buena Gardens and the Metreon. The Yerba Buena/Moscone Muni Metro station sits at the complex's southwestern corner and links to Caltrain; Powell Street station, served by BART and Muni, is two blocks away.

The roof features solar panels that have generated electricity since 2004 as part of San Francisco's clean energy efforts. This installation was one of the city's early applications of large-scale solar power for commercial buildings.
