The mouth of Hell

In 1962, a small fire in a city of Pennsylvania called Centralia caught up with an exposed vein of anthracite coal located underground. The flames on the surface were extinguished, but the coal under the town continued to burn for many years, and in 1984 the fire forced people who lived there to evacuate the city. Currently, this town is an abandoned and deserted place, and the fire which is still burning beneath the town, has enough coal to feed it for other 250 years more. This is not only one of the most mysterious places in the world, but it also looks pretty scary too, don’t you agree?
