Newgrange with the Cursus in the next field. The Cursus is a mystery as is Newgrange itself, I would guess that is was used to plan the building location of Newgrange using the rising sun locations during the year, same as the Cursus at Stonehenge.
I am from Lahinch in County Clare and have been visiting the ancient sites of Ireland since 2015. I am very interested how the doorway of stone circles always seem to be purposefully pointed at the sunrise or sunset at key times of the year. This suggests that the people who built these forts thousands of years ago had a deep understanding of astronomy and were more advanced than we give them credit for.
I also film and edit music videos, see below for my latest work -
