What do you think about this?
Off the coast of Pohnpei, a small island in the western Pacific, lies a ruined city that should not be possible. It is called Nan Madol, and it is built out over the water, more than a hundred artificial islets laced together by canals, which is why some call it the Venice of the Pacific. But it is what the islets are made of that stops people cold.
The whole city is constructed from massive columns of black basalt, long rod like stones that formed naturally in a volcano, some of them weighing several tons. They are stacked like giant logs to build walls over twenty feet high. In total, the site holds close to a million tons of stone. It was the capital of the Saudeleur dynasty, built up over centuries beginning around eight or nine hundred years ago.
Here is the puzzle. There are no quarries at the building site. The basalt came from elsewhere on the island, and somehow those enormous columns were moved across land and water and lifted into place, by a people with no metal tools, no pulleys, and no written record of how they did it. Local legend simply says two sorcerers made the stones fly through the air.
Makes you wonder how a society we tend to picture as small and simple moved a mountain of stone into the sea and built a city on it.
Lost engineering we have underestimated, or a mystery the islanders themselves could only explain with magic? What do you think raised Nan Madol?
