This TERRIFYING Looking Hole in a Giant Lake Does Something Impressive to The Water It Sucks Up

Spillways are designed to control water in dams, but this one looks more surreal than practical. The Covao do Conchos Spillway was built in 1955, and it’s part of the Conchos Dam in Portugal.

The 4,984-foot-long tunnel leading to the dam is a seriously impressive display of human engineering, but most people are more impressed with its stunning form than they are with its function.

While the drone provides us with breathtaking aerial shots of the spillway, it never gets too close. As beautiful as the Covao do Conchos is, it could mean certain death for those unfortunate enough to get caught in its current. This world is full of bizarrely beautiful wonders.
