Built in 1914, the Oakland Auditorium was renamed the Henry J. Kaiser Convention Center after its renovation in 1984. It achieved landmark status in 1979. In addition to its very interesting history, the Auditorium is compelling because of the seven very beautiful A. Stirling Calder facades that adorn the entrances on its north side. These are located on the 12th Street/Lake Merrit Blvd side of the building across the street from the lake. You can find more of Calder's work here and here.
