Gorsedd Circle The Gorsedd Cir cle is a stone circle in Fishguard, Wa les. T he Gorsedd Stone s are a Welsh tradition of modern stone circles constructed for the National Eisteddfod of Wales. These stone circles can be found at several locations, including Ab erdare Park and A nglesey. They are typically 20 meters wide and have 12 stones on the circumference with a level stone in the circle. A further stone is usually set back from the circumference, the central stone is called the Logan Stone. Coordinates 51.996431,-4.975040 Stone Circle Gorsedd Circle is a typical stone circle but has 13 stones on the circumference with one inset. It was erected in 1936 and has the names of the parishes inscribed on each stone. Ceremony During the opening ceremony, the Archdruid stands on the Logan Stone facing the Stone of the Covenant. Two stones mark the entrance and are called the Portal Stones. These mar k the midsummer and midwinter sunrises. Gorsedd Circle (no edit) Archeology77 ©
Alignment de Lutry
The Alignment de Lutry is thought to be dated to the Neolithic 4500/4000 bc, with the smaller stones aligned towards the spring solstice and the larger towards east and the winter solstice.
The alignment is located in the town of Lutry, in the canton of Vaud. It was discovered in 1975, but the current monument is a reconstruction from 1986 built a few dozen metres from the original location.
It is currently about 250m away from Lake Geneva and part of the Swiss cultural heritage.

Alignment
There are 10 small stones, 8 large stones split 3/5 by a small stone, with the whole monument in a shallow curve (A small stone has been replaced, there are 23 stones in total).
The large stones are aligned at 30° (with a length of 36 feet) to the northwest, and the smaller stones fall on a circumference of a circle of radius 47ft, aligned south at maximum tilt.
The centre of this circle from a line of 57° falls on the small stone that splits the large stones 3/5, the end large stone at 30° also aligns with the centre.
Using these numbers then the sides of a 90° triangle would be 47ft, 23.9477ft, and 52.749ft.
If considering obliquity from mid point 1584 years past 1985, then the following would give a year of 2365 bc.
23.9477−23.253=0.6947
0.6947÷1.2=0.57892
0.57892×10250=5933.89
5933.89−1584=4349.89
4349.89−1985=2364.9 bc
This would equate as 6.742° for tilt and, if subtracted from 30° would leave 23.258°, this number is 0.005° off the currently considered mid point obliquity.
30−6.742=23.258
Conclusion
This area of Switzerland was popular from 2700 bc then again in the 1st century bc.
The area is prone to glacial melt, and from other monuments in the area, it has shown that melt waters could raise and fall.
Discovery of monuments below the water line shows that the water level was probably a lot lower, allowing for the builds. When water levels rose, these monuments were built again, but at a higher altitude, they might have also represented a wider range of points.
For the Alignment de Lutry, they used a triangle, circle, and tangent, which gave obliquity for the year 2365 bc.
The number for mid point obliquity is very similar to the Earth's tilt at maximum tilt, and if it represented this, then the 47ft radius of circle could then represent the latitude for the location as 46.503224°. The tilt angle of 6.742° is very near to the longitude 6.684913°.
The two, obliquity and coordinate, are also very near to 47.
46.5°+0.6947°=47.2°
