Social Hall, Social club building on Alcatraz Island, San Francisco, United States

The Social Hall, also called the Officers' Club, stands on the northwestern side of Alcatraz Island, near the Power House, water tower and former Military Chapel. The burned shell of the club remains after the 1970 fire; inside it once held a small bar, a library, a large dining and dance floor, a billiards table, a ping pong table and a two-lane bowling alley.

The Social Hall served as the social club for Federal Penitentiary workers and their families on Alcatraz, who could unwind there after inmates were locked up at 17:30. During the Occupation of Alcatraz in 1970, a fire of disputed origin burned the building down, leaving a shell that still stands on the island's northwestern side.

The Social Hall was the social centre for Federal Penitentiary staff and their families on Alcatraz, who gathered there after inmates were locked up at 17:30. The club organised ice cream and watermelon feasts, Halloween and Christmas parties, and fundraising for events held in the hall or on the Parade Grounds. Its name comes from this role as the island's social venue.

The Social Hall is a burned-out shell on the northwestern side of Alcatraz Island, reachable only by ferry from San Francisco and then on foot; the island's routes are steep in places. The structure stands near the Power House, water tower and Former Military Chapel, and its ruin is viewed from outside rather than entered.

The 1970 fire left only a shell of the Social Hall, and that roofless ruin is what visitors see today. The blaze broke out during the Occupation of Alcatraz, and its origins remain disputed. The gutted walls stand near the Power House, water tower and Former Military Chapel.
