The world is a wonderful place full of secrets that we have yet to uncover. Most of those secrets hidden by nature, but at times, man creates something that is so remarkable, you can’t help but wonder how it all came to be. The curiosity that rises from learning about these forbidden locations is all the more intriguing as most will not allow you to visit or even see the location. Many have reasons that relate to human survival, and some are there for when we are gone. All, though, are infinitely interesting.

Located in Vatican city, these archives are one of the most important for the Catholic church. Closed off to all for years, it contained state papers, papal account books, and other significant documents that were accumulated over the centuries. In 1881, Pope Leo XIII allowed some researchers and scholars to access the contents, but it was limited to very few. Today, highly qualified scholars my request access, but they are given strict limitations on what they can view and what they are allowed to do.

Southwestern France is home to one of the best preserved examples of prehistoric art.

The caves are guarded and visited once a week for just moments by a guard to ensure all is safe.

Area needs little introduction. The American military base has long been a breeding ground of conspiracy theories and cover-up stories based on the landing of an alien spacecraft. While this is most likely not the true story, it is a highly guarded area, likely used to test experimental weapons, aircraft and other research for the U.S. military.

This volcanic island located in the Vestmannaeyjar Archipelago off the coast of Iceland is one of the youngest islands on earth. It is heavily guarded and forbidden due to the scientific information that can be obtained by allowing it to flourish unimpeded by human intervention. It was formed due to a volcanic eruption that lasted four years (1963-1967).

Svalbard Global Seed Vault, Norway

croptrust.org

My personal favorite on the list is the seed vault located in the Svalbard Archipelago. This is primarily because of the stories that could be told about this vault. It seems ripe for a disaster movie, playing the central role. The Global Seed Vault is between Norway and the North Pole and is home to 1 million of the 4.5 million seed samples it is prepared to hold. Ultimately, it is a safety net created by man to protect against crisis of any sort and help repopulate nature when needed.

Coca-Cola is the soda brand for many in the U.S. and the formula has never been replicated. This is partly due to the high security in which the formula is guarded with only a handful of individuals knowing the exact mixture. This is the Fort Knox of drinks and one that few get to experience.

The name alone gives you a good idea while Illha de Quimada Grande, or the Island of Snakes, is off limits. Near Sao Paulo, Brazil the island is notorious for a high population of snakes, including the Golden Lancehead Viper. The viper has venom that is so powerful it will melt human flesh. Because of this, the Brazilian government has banned visitors from stepping foot on the island.

It is strange that a museum would be forbidden to outsiders, but this educational museum in Nanjing, Eastern China is closed to anyone outside of Chinese visitors. Even then, they are forbidden from taking photos, as the collection is too sensitive for foreign eyes.

Dulce Base, New Mexico

Close to the Colorado border in Northern New Mexico is an entrance that seems to be straight out of a sci-fi movie. It is believed to be a town that holds an underground facility with unheard of experiments and technologies being developed. The thoughts are that human-animal hybrids, human-alien hybrids, and advanced technologies are worked on, though there is no proof to support any of these claims.

Somewhere in the Southern Ural Mountains of Russia, this town has been closed due to reported nuclear missile connections. It was originally a town that housed, and protected some of the most advanced weapons of the time and may have even allowed for automatic missiles that could be activated from anywhere. No official statement has been released about these claims.

Chichen Itza Pyramid, Mexico

The age alone of these ruins likely points to the main reason this is an off-limits area for human visitation. This is the best preserved example of the Mayan ruins still in existence, and while the area sees 1.5 million visitors a year, the El Castillo pyramid, which is the most famous feature of the location, was closed to the public after a woman died tumbling down the pyramid in 2006.

It could be argued that this tomb is a minor wonder of the world. Famous for the complicated network of caverns filled with items the emperor would need through the afterlife, such as a clay army, known as the Terracotta Army, it is not visited to show respect to China’s first Emperor, Qin Shi Huang, founder of the Qin Dynasty.
