There are thousands of islands in the world. Many have their own rich histories, culture, and mysteries. A degree of isolation comes with the territory, but this can sometimes create strange natural dynamics and human behavior.

We tend to think of ancient civilizations like those in Rome and Egypt as holding all our historical secrets. We look to the landmasses in Europe, the Americas, the Middle East, and Asia for even more archaeological clues. But islands with a lot of foot traffic in the past can also hold missing pieces from history as well as extinct cultures and unusual graves.
