A ghost town, deserted city, extinct town, or abandoned city is an abandoned settlement, usually one that contains substantial visible remaining buildings and infrastructure such as roads. A town often becomes a ghost town because the economic activity that supported it (usually industrial or agricultural) has failed or ended for any reason (e.g. a host ore deposit exhausted by mining). The town may have also declined because of natural or human-caused disasters such as floods, prolonged droughts, extreme heat or extreme cold, government actions, uncontrolled lawlessness, war, pollution, or nuclear and radiation-related accidents and incidents. The term can sometimes refer to cities, towns, and neighborhoods that, though still populated, are significantly less so than in past years; for example, those affected by high levels of unemployment and dereliction.[1]
Some ghost towns, especially those that preserve period-specific architecture, have become tourist attractions. Some examples are Bannack, Montana and Oatman, Arizona in the United States; Barkerville, British Columbia in Canada; Craco and Pompeii in Italy; Aghdam in Azerbaijan; Kolmanskop in Namibia; Pripyat and Chernobyl in Ukraine; Dhanushkodi in India; Fordlândia in Brazil and Villa Epecuén in Argentina.
