Today is a magical day for all kids and kids at heart as Disneyland turns 60. To celebrate the birthday of the “the Happiest Place on Earth,” Disneyland Resort’s official Twitter page shared rare photos, gifs and videos from the theme park, in addition to “live-tweeting” events from the opening day as though they were happening today.

The Southern California landmark forever changed the world of amusement parks.
