The Integratron is a structure designed by ufologist and contactee George Van Tassel. Tassel claimed the Integratron was capable of rejuvenation, anti-gravity and time travel. He built the structure in Landers, California (near Joshua Tree), supposedly following instructions provided by visitors from the planet Venus. The Integratron machine was started in 1957, the structure erected in 1959. It was financed predominantly by donations, including funds from Howard Hughes.
