Unsolved Mysteries That Will Fascinate You


#12 Kryptos

Right outside the CIA’s headquarters in Virginia, you will see a strange statue that stands at 12 feet tall. Made using curved copper, this was first seen in 1990.

With a peculiar Greek name, “Kryptos,” meaning “hidden” or “secret,” this statue features 1,800 characters.

These characters make up four messages, out of which only three have been solved.
