NAN MADOL

[EBE]

 

 

Nan Madol has earned the awe of many archaeologists because the islands are made almost entirely of basalt walls that are 18 to 25 feet high and about 17 feet thick.

Basalt is a stone formed by volcanic lava.

The walls are built by alternately stacking the stone logs in a criss-crossed pattern, as we can see below.

The city?s interior was covered with coral rubble to form an elevation that high tides cannot reach.

 

 

Archaeologists estimate that a whopping 250 million tons of these basalt logs are needed to construct the whole city.

But the question archaeologists have yet to answer is,

?How in the world were these walls constructed so high,

given how heavy the basalt logs were?? In fact,

each basalt log can weigh as much as 50 tons.
