Yes Jim at the Newport Tower Museum has written numerous books that explains who built the tower. Tomorrow (winter solstice) we meet at the tower and watch the key stone light up and the sun shines through two windows at the same time really cool I go every year.
Contrary to what is believed, it is not an old windmill. It is the exact dimensions of a templar church.
The keystone is not shaped "exactly like" the tablet lady liberty holds.
In one of the pictures (if not, a few), you will see at the top of the archway, in the center, a "keystone" which is shaped exactly as the one lady liberty of The Statue of Liberty is holding. This tells me that this structure was built by The Knights Templar.
