The entrance stone.
At the end of the passage there are three chambers.
These chambers contain basins, with burnt remains of five (?) humans, along with pieces of jewellery.
So it is presumed that this is a burial chamber of sorts.
This is the stone at the back of the building, again showing Spirals, Lozenges or
Zig-Zag formations.
this
"Zig-Zag" motif is found on the entrance stone and repeated along the passage and again inside the chamber.
OK, so here is the "new" part of our understanding.
This is an interesting theory but remember it is only a theory, for now anyway.
I have heard that the resonant frequency of the inside of the man made passage was constructed in such a way that the reverberations produce some unusual and interesting effects.
The resonant frequency is 110hz, the frequency of the male baritone, the second lowest singing voice (chanting).
And when the inside of the passage is filled with smoke or mist, the resonant frequency reverberates turning the smoke into the
Zig-Zag formation!.
"Archaeologists have suggested that chanting, singing and drumming at these sites would have produced reverberating echoes that might have been interpreted as voices of spirits or gods; they may also have induced physiological and psychological changes in people, adding to...

Built at the same period these make a much larger complex.
"It is clear from the orientation of the passage-mounds that the whole complex was devoted to accurate measuring of both the lunar and solar cycles simultaneously."
Celestial significance?
Court tomb
here are over 350 known court-tombs in the whole of Ireland.
and Wedge tomb.
Of course similar constructions can be found in other parts of Europe and indeed the world but my focus is on Ireland.
Which is rich in prehistoric myths and legends about these enigmatic people and structures.
For an example these were referred to as fairy mounds.
