You won't find any gambling at Avalon's Catalina Casino: The name actually refers to the Italian word for "gathering place." The glamorous 1929 structure was commissioned by William Wrigley, Jr., and quickly became the island's best-loved (and most visible) landmark. The circular white building is a striking example of Art Deco architecture, with Spanish-inspired floors and vivid murals created with gleaming Catalina tiles. Big-name entertainers have performed in the Ballroom, while the Avalon Theatre—with its Art Deco murals and classic 1929 pipe organ—still screens first-run movies on the lower level. Tours of the building are offered.
