The Door to Hell
This place in Uzbekistan is called by locals “The Door to Hell”. It is situated near the small town of Darvaz
The story of this place lasts already for 35 years. Once the geologists were drilling for gas. Then suddenly during the drilling they have found an underground cavern, it was so big that all the drilling site with all the equipment and camps got deep deep under the ground. None dared to go down there because the cavern was filled with gas. So they ignited it so that no poisonous gas could come out of the hole, and since then, it’s burning, already for 35 years without any pause. Nobody knows how many tons of excellent gas has been burned for all those years but it just seems to be infinite there.
Mysterious Holes of Russia
From the end of 1980s a strange phenomena is happening in some Russian forests. People find strange, deep holes.
They appear in the dense forest, in the places you can’t get on the car or truck to bring any device to drill the ground. There is no any soil that should be taken from such deep holes is found.
People go down to one of such holes but it just finishes with nothing. There are no any reasonable ideas on how these holes appear and what they are being used for.
The mouth of Hell
In 1962, a little fire in Centralia (Pennsylvania) migrated into an exposed vein of anthracite coal under the town. The flames on the surface were successfully extinguished, but the coal continued to burn underground for many years, so that in 1984 the fire was completely out of control and the city had to be evacuated.
Nowadays, Centralia is an abandoned and ghostly place. The fire still burns beneath the town and there is enough coal to feed the fire for up to 250 years.
Hill of Crosses in Lithuania
It has more than 50,000 crosses on it, and no it is not a cemetery.
The reasons for the crosses to be there is that there is a story that each one who would put his own cross on this mountain would become a lucky guy, so thousands come here and install their custom crosses.
They say this tradition appeared before the Christianity came to Lithuania and Russia and is of pagan origin.
The ghost town buried in the sand
Kolmanskop is a ghost town in southern Namibia, a few kilometres inland from the port of Lüderitz. In 1908, Luederitz was plunged into diamond fever and people rushed into the Namib desert hoping to make an easy fortune. Within two years, a town, complete with a casino, school, hospital and exclusive residential buildings, was established in the barren sandy desert.
But shortly after the drop in diamond sales after the First World War, the beginning of the end started. During the 1950′s the town was deserted and the dunes began to reclaim what was always theirs.
Soon the metal screens collapsed and the pretty gardens and tidy streets were buried under the sand. Doors and windows creaked on their hinges, cracked window panes stared sightlessly across the desert. A new ghost town had been born.
