20,000 Leagues Under the Sea | DISNEY THIS DAY | August 5, 1955

On this day in 1955, the 20,000 Leagues Under the Sea Exhibit opened in Disneyland’s Tomorrowland. Guests could explore several Nautilus submarine sets and props, many of them screen-used, including a view of the sub’s exterior through a porthole, the salon and giant squid, the pump room, the chart room, the diving chamber, the wheelhouse, and Nemo’s famous pipe organ, which is now located in the Haunted Mansion. The exhibit was popular and remained open for 11 years. [70 years ago in 2025]
