Centralia
Location: Centralia, Pennsylvania, United States
Story: The entire city of Centralia was condemned by the state of Pennsylvania and its zip code was revoked. The road that once led to Centralia is blocked off. It is as if the city does not exist at all, but it does, and it has been on fire for almost fifty years. In 1962, a fire broke out in a landfill near the Odd Fellows cemetery. The fire quickly spread through a hole to the coal mine beneath the city, and the fires have been burning ever since. Smoke billows out from cracks in the road and large pits in the ground randomly open up releasing thousand degree heat and dangerous vapors into the air. The city has been slowly evacuated over the years, though some residents have chosen to stay, believing that the evacuation is a conspiracy plot by the state to obtain their mineral rights to the anthracite coal reserves below their homes. Smells like lawyers to me.
Abandoned since: still marginally occupied by 10 or so brave souls
