The medieval town of Craco, Italy, can be dated back to 1060. In 1891, the population of Craco stood at well over 2,000 people. Poor farming, earthquakes, landslides, and war all contributed to a mass migration. In 1963 the remaining 1,800 inhabitants were transferred to a nearby valley and the original Craco remains in a state of crumbling decay to this day. The relics of Craco include a university, a castle, churches and several plazzas.
