Menwith Hill Air Force Base
The United Kingdom’s Menwith Hill Air Force Base is most likely the location that most closely resembles the United States Area 51. Local residents are so perplexed by the activities taking place inside the mysterious 550-acre base with its numerous domes that they have filed legal complaints against the government in an effort to learn more about the activities taking place inside the base. However, their efforts have not been successful as of yet.

Mercury, Nevada
In the 1950s, Mercury, Nevada, was a thriving town that had many businesses, restaurants, and a large number of people working in the nuclear industry. Indeed, nuclear testing in the United States is to blame for another restricted region, this one is the planet, Mercury. There are rumors that there are still several hundred people living in the town at the present day, but no one can confirm this since the only outsiders who are permitted in the village are credentialed, government researchers.
