Today we are giving you information about the ancient city of Hierapolis in Turkey, where a very ancient temple is built and this temple is said to have a 'Gate of Hell', which is very mysterious. It is said that if anyone goes inside this gate, they'll never come out of it.
Also, let us tell you that after coming in contact with this temple, everyone dies from humans to animals and birds and till many years ago this place remained mysterious because people believed that the people who came here died and there are many secrets behind it. Also, because of the frequent deaths here, people started calling the doors of this temple as the 'Gate of Hell' and it is said that in Roman times people were very afraid to go there due to fear of death.
On the other hand, the mystery of mysterious deaths of people has been solved by scientists. Scientists believe that poisonous carbon dioxide gas is continuously leaking out from under the temple, due to which humans and animals and birds start dying. According to research done by scientists, a large amount of carbon dioxide gas is found in the cave below the temple. Also, where usually only 10 per cent carbon dioxide is able to put any person to sleep in just 30 minutes, the amount of this poisonous gas inside the cave is up to 91 per cent.
