The California State Building was situated on the west side of the California-Pacific International Exposition's Plaza de America, adjacent to the Hollywood Motion Picture Hall of Fame. Architect Richard Requa designed the structure to represent the similarities in mass and form between ancient Mayan, Indian Pueblo and modern 20th-century architecture. The large rectangular building featured plain unadorned walls, decorated with vine-filled planter boxes at the parapet level, and a central concave entrance portal, decorated with Mayan style fibre-wallboard ornamentation. Four large vertical panels, created from squares of fibre-wallboard painted and varnished to imitate polychrome tile, were located above the entrance and depicted symbolic scenes of the story of California. Within the spacious building California's agriculture, commerce, industry, education, architecture, art, communications, highways, and police and military organizations were represented by many comprehensive displays. A detailed relief-map illustrated the state's water resources and the central valley water project; while several large murals portrayed California's history and lore.
