Winterland Ballroom (more commonly known as Winterland Arena or simply Winterland) was an ice skating rink and music venue in San Francisco, California. The arena was located at the corner of Post Street and Steiner Street. It was converted for exclusive use as a music venue in 1971 by concert promoter Bill Graham and became a common performance site for many famous rock artists. Graham later formed a merchandising company called Winterland Productions which sold concert shirts, memorabilia, and official sports team merchandise.
