Forget about colored marbles and check out this great monolith in Nigeria. Amazingly, this monolith named Zuma Rock is 725 feet and one remarkable thing about it is that Zuma Rock has been used for defense in ancient wars. Many myths have come and gone because of this monolith’s face-like formation – it’s up to you to believe it or not. You just have to go up north in Abuja and you’ll be able to see this magnificent wall rock.
