Death
Within a few years of the opening, Disney began plans for a new theme park and Experimental Prototype Community of Tomorrow in Florida. It was still under construction when, in 1966, Disney was diagnosed with lung cancer. He died on December 15, 1966, at the age of 65. Disney was cremated, and his ashes interred at Forest Lawn Cemetery in Los Angeles, California. After his brother's death, Roy carried on the plans to finish the Florida theme park, which opened in 1971 under the name Walt Disney World.
