Hero was established in 1942, and was named after Major General Andrew Hero. In World War II, Montauk was a probable invasion point by submarines. They started acquiring more land in the area, as well as started building docks, hangers, barracks, and a torpedo testing facility. Camp Hero grew to 278 acres, it was like its own little town with recreational facilities, barracks, power stations, training facility, target range and control center. Camp Hero was built to look like a New England fishing town, the bunkers had windows painted on them, and the gym was built to look like a church. When World War II ended in 1949, the base was shut down and used for training the Army Reserve. The Naval facilities were left abandoned and guns were dismantled. The Cold War then began and a radar tower was immediately built. In 1953 the camp was changed to the Montauk Air Force Station. Camp Hero was then closed down because the soviet bombers could fly above where the artillery could reach. It was donated to the state of New York but was unused because it was so close to the high security air force station. The Montauk Air Force Station developed or tested all of the new state of the art technology, like magnetic memory, light pens, keyboards and more. The Air Force Station was closed in 1981. The Montauk Project started in the 1980's. It is consider a conspiracy theory because it is not confirmed by the government, but many other confirmed experiments have happened during this time. The Montauk project partially inspired the popular television show "Stranger Things". Many ideas came from the "The Montauk Project: Experiments in Time" from someone who formerly worked at Hero and tells what he saw during his time there.
Police regularly patrol, wouldn't recommend trying to get into the buildings.
