Stonehenge.
The first verse describes the mystery that is Stonehenge. Although there are theories, we're still not absolutely positive who built it, how it was built, or why.
The second verse refers to the body of Stonehenge and the damage humans have caused. Each of the vertically-set stones weigh roughly over 5 tonnes, but tourists and passers-by have damaged and vandalized some smaller boulders also part of Stonehenge. There may also have been even more stones that were part of the broken circle that have now gone. Of course, rocks are lifeless, which explains the "life currents" mention.
The final verse explains some of the different theories developed for the purpose of Stonehenge. Some have said it was used to mark dates with the help of the sun's alignment, it may have been a burial ground, or even a temple of worship.
The capitalized words in the hint were used quite literally: Stonehenge is made of STONE, and it is one of the WONDERS of the world.
