3. Unit 731 Experimentation Camp, Japan
At the beginning of World War II, 3,000 Japanese prisoners and 250,000 Chinese died from brutal experimentation conducted by Japanese scientists within this complex now known as Unit 731. Men, women, and children were subjected to vivisections, which are basically live dissections without anesthesia. Prisoners had limbs amputated in order to study blood loss. Those limbs that were removed were sometimes re-attached to the opposite sides of the body. Some prisoners had their stomachs surgically removed and the esophagus reattached to the intestines. Parts of the brain, lungs, liver, etc. were removed from others. In other tests, subjects were deprived of food and water to determine the length of time until death, placed into high-pressure chambers until death, experimented upon to determine the relationship between temperature, burns, and human survival, placed into centrifuges and spun until death, injected with animal blood, exposed to lethal doses of x-rays, subjected to various chemical weapons inside gas chambers, injected with sea water to determine if it could be a substitute for saline, and burned or buried alive.
4. Edinburgh Vaults, Scotland
Underneath the busy streets of modern Edinburgh lie the Edinburgh Vaults, which have been abandoned for nearly two hundred years and were only rediscovered in the mid-1980s. Used as cellars, workshops, and residences by the businesses that plied their trades on the busy bridge since 1785, they were later abandoned due to the unpleasant atmosphere. These days locals claim the place is haunted due to a number of strange incidences that have taken place over the years.
