6 Deepest Holes Humans Have Ever Dug by Hand

How deep can humans possibly dig? Woodingdean Water Well has the title of the deepest hand-dug well in the world, but at first sight, it’s just a small covered well you wouldn’t even assume that it’s there. It’s as deep as the Empire State Building is tall – 1,280 feet straight down into the dark, wet ground. It was only used for four years. Let’s discover this and other amazing wells and mines around the world.
