Magic Kingdom, Disney's Contemporary Resort and Disney's Polynesian Resort all opened 44 years ago today, becoming the first pieces of Walt Disney World.

Many of the original attractions are still around today, including Jungle Cruise, Country Bear Jamboree and The Hall of Presidents.
How proud would Walt be today
