Greatest Unsolved Mysteries, Ranked

One code has resisted 600 years, one colony vanished leaving a single carved word, and one 2,000-year-old machine still shouldn't exist.

The top 3

  1. Codes Nobody Can Crack: Ranked by years unsolved: a 600-year-old book, a still-secret sculpture, and a cipher pointing to buried treasure.
  2. Vanished Without a Trace: Three disappearances no search has ever solved: a ghost ship, a lost colony, and a lost aviator.
  3. Ancient Builds That Baffle Science: Feats of engineering we still can't fully explain, ranked by how far ahead of their time they were.
