Did you know that there’s a river in Portugal that appears to have a sinkhole in it, or as some have jokingly described it, “a portal to the center of the Earth”? It’s true! Well….at least it’s partially true. You can see it for yourself below!
As you can see it’s a visual marvel, but actually a man made one! It’s called Covão do Conchos, and while it certainly looks breathtaking and strange, it’s actually a spillway that is part of the Conchos Dam, near Guarda. The dam was built in 1955, but thanks to recent drone footage gone viral, the spillway is now being seen all over the world, in all its majestic and mysterious glory!
