The Starcade isn't the only relic from Tomorrowland's past. Hints of the area's 55 year history can be found throughout the land... if you know where to look.
From 1957 to 1967, Monsanto sponsored an exhibit near the entrance to Tomorrowland, called the House of the Future (photo ©Disney). Touring the inside of the house, guests could see a variety of innovations that promised to make future living easier and more comfortable, from plastic furnishings to a microwave oven and electric dishwasher.
After a new Tomorrowland debuted in 1967, the House hosted its last visitors and closed for good. The stories are legend about how the House of the Future was resistant to demolition. It ultimately had to be torn to pieces to be removed. Not all of the former attraction is gone, however. In the garden near Pixie Hollow, where the House of the Future once stood, you can still find its reinforced concrete base. It's been painted green to better blend with the current surroundings, but it stands testament nonetheless to a vision of future past.
A caveat, if you wish to seek out this bit of Tomorrowland history for yourself: The above photo was taken several years ago, when the area was Ariel's Grotto. Now that Pixie Hollow occupies this space, I can't attest to how visible the platform still is.
