The Catalina Casino was built on a site formerly known as Sugarloaf Point. The site was graded for the planned construction of the Hotel St. Catherine, which was instead eventually built in Descanso Canyon. When chewing gum magnate William Wrigley Jr. bought the controlling stake in Catalina Island in 1919, he used this cleared site to build a dance hall he named Sugarloaf Casino. It served as a ballroom and Avalon's first high school, until it became too small for Avalon's growing population. In 1928, the Sugarloaf was razed to make room for a newer casino building. Sugarloaf Rock was further blasted away to enhance the Casino's ocean view.
