UFO shape structures in the Arizona desert
Just south of Casa Grande is a group of unique structures known as "The Domes". The collection of concrete buildings have been abandoned for almost thirty years and are an attraction to both tourists and Pinal County locals, though it should be said that they are on private property and you must get approval to enter the property. There are many mysteries when it comes to the domes and some say that the site is home to something sinister. Many report seeing ghosts and hearing voices, while others say they hear tapping sounds on their vehicles when approaching the location. Some even say that the Domes are frequented by Satanists, where they perform rituals and animal sacrifices.
