Potosi Town, Venezuela

Another victim of dam-building frenzy thanks to over-generous foreign aid was the town of Potosi, which saw its residents relocated in 1985 before the town became submerged in favor of a hydroelectric dam.

For the next two decades, the only thing visible was a single cross on top of a church.

However, in 2010, the water levels began to drop, slowly revealing an underwater ghost town with a gothic church that was just as covered in mildew as the cross on its tower.
