There have been many claims of alleged underground bases in different parts of the planet, most of which are believed to be serving to the a̳l̳i̳e̳n̳s as their experimental or military power testing grounds. Here is a list of such top 10 underground a̳l̳i̳e̳n̳ bases which are feared as the hub of a̳l̳i̳e̳n̳ operations on Earth.
Underground a̳l̳i̳e̳n̳ bases in Europe
(1) Initially commissioned as the official development facility of gas mask technology during World War I, the Porton Down base in Wiltshire, England is believed to be one of the most active underground a̳l̳i̳e̳n̳ bases of the world. The fact that Wiltshire gets maximum share of crop circles being made on its fields supports that fact that a̳l̳i̳e̳n̳s are very active in this part of the world.
(2) A large iron plate was discovered by a laborer in the fields of Staffordshire in England, the hatch of whose was oval and large with an iron ring mounted on it. The plate served as a closed gate to a tunnel which is believed to connect to an underground a̳l̳i̳e̳n̳ base. The whole thing is mentioned in the 18th Century historical documentary book titled ‘A history of Staffordshire’.
Underground a̳l̳i̳e̳n̳ bases in Canada
(3) One of the iron mines in Newfoundland was being shut down owing to various strange events that occurred in the mine when it was dug deeper than the other mines in that area. As per eye witnesses, shadows of beings of unusual shape and structure were being spotted and various mysterious things happened inside the mine, which compelled people to believe that it was serving as an underground a̳l̳i̳e̳n̳ base on earth.
(4) The Valley of the headless man or the Nahanni Valley in Canada is a mysterious piece of land as people entering the valley are mostly founded dead with their heads being severed brutally. Multiple such incidences have infused the fear in the minds of the locals that this area is being captured by a group of hostile a̳l̳i̳e̳n̳s who cause such vicious de̳a̳t̳h̳ to anyone who enters ‘their’ area.
Underground a̳l̳i̳e̳n̳ bases in Russia
(5) Russia’s Roswell or the Zhitkur Base in Russia is a hub of different a̳l̳i̳e̳n̳ operations that are being carried out by e̳x̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ beings. Officially, the base is supposed to serve as a rocket launch facility, but the reality is that all sorts of secret researches by a̳l̳i̳e̳n̳s are conducted under the snows
Underground a̳l̳i̳e̳n̳ bases in America
(6) If Hopi legends are to be believed, the caves near the confluence of Little Colorado and Colorado rivers used to be underground homes of ant people who were friendly with local humans. Some of these caves have been explored to discover Central American, Egyptian and Oriental type artifacts which has made people believe that this area served as a secret underground a̳l̳i̳e̳n̳ base.
(7) As per local folklore there are many tunnels beneath Mt. Shasta in California which leads to an underground a̳l̳i̳e̳n̳ base. The fact that California is one most those states that has maximum U̳F̳O̳ sightings makes it easy to believe that the U̳F̳O̳s come to meet up with the a̳l̳i̳e̳n̳s stationed at the underground base beneath Mt. Shasta.
(8) Another entrance to a large underground city can be found near Mt. Lassen in California’s Tehama County. The residents of Manten, the city at the foot of Mt. Lassen have known about this underground base for long and believe it to be an operational hub of a̳l̳i̳e̳n̳ visitors.
(9) The most famous underground a̳l̳i̳e̳n̳ base is the Dulce Base in New Mexico. This underground base is believed to have multiple lairs, with each lair being the ground of horrific genetic experiments on humans and other forms of life on the earth. A population of 18,000 a̳l̳i̳e̳n̳s is believed to inhabit the Dulce Base.
(10) What is being covered up as a secret military air force research and testing grounds is actually an underground a̳l̳i̳e̳n̳ base where captivated a̳l̳i̳e̳n̳s from the 1947 Roswell U̳F̳O̳ crash are kept and studied. We are talking of A̳r̳e̳a̳ 51 located in the deserts of Southern Nevada, the most discussed and most hyped a̳l̳i̳e̳n̳ base under the soils. It is believed that a̳l̳i̳e̳n̳ spacecrafts and a̳l̳i̳e̳n̳ corpses are being studied here and reverse engineering is also being conducted on the a̳l̳i̳e̳n̳ spaceships.
