Roman Amphitheatre of Uthina The Roman Amphitheatre of Uthina is located in Uthina , near Tunis, Tunisia . Building for Uthina began in 40 BC and continued through to 135 AD. The amphitheatre may have been a later addition to what was already a large town. Also located there were a fortress, cisterns, an aqueduct, a triumphal arch, a theatre, and a basilica with a circular crypt . Coordinates 36.608598,10.169214 Description The amphitheatre, partly buried, measures 113 by 90 meters. The arena measures 58 by 35 metres, giving surface areas of 7988 and 1539 square metres respectively. There are four entrances, two main entrances at each end, with the seating area supported by three tiers of columns and arches. (Although these are no longer there, measurements and amphitheater descriptions rely on a complete building.) Measurements for the amphitheatre on site are 12 0 by 89 metres, with the arena measuring 67 by 36 metres. The surface areas measure 10680 an d 24...
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°
