Grianan of Aileach The Grianan of Aileach is a hillfort on Greenan Mountain at Inishowen in County Donegal, Ireland. The main structure is a stone ringfort, thought to have been built by the Northern Uí Néill, in the sixth or seventh century, it has been identified as the seat of the Kingdom of Ailech and one of the royal sites of Gaelic Ireland Coordinates 55.023780,-7.427488 Measurements The altitude at the location is 225m with an average of 215m in the area around the ringfort. The ringfort is 100ft wide (30.48m) with the walls 16.4ft (5m) high. Alignment  The following shows that at current alignment, the hillfort's angles don't mean anything, but at 2° further rotation, there is a connection Assuming that the ringfort is dated to 700 ad, then the tilt from construction would be 2°. The entrance is measured at 3° at maximum tilt, then adding 2° would give an angle of 5° or 14° on the far wall. If the exit (from outside) is at 12° the other door north/south is at

Pella Pella is an ancient city located in Central Macedonia, Greece, which is best known as the historical capital of the ancient kingdom of Macedon and the birthplace of Alexander the Great. Currently, the area is being excavated so that it can open for the public in 2021. On site, there is the Pella Archaeological Park, Museum, and Ancient Agora of Pella. The Ancient Agora of Pella is the largest building on site with a measurement near 243m (800ft) at an angle of 2°. Most buildings partly buried also follow this alignment with a few at 5°, although if the part buried side isn't included, then the measurement would be 210m (689ft). Coordinates 40.756672,22.518959 Measurements The 2° angle of most buildings equates in years as 695 ad but is past maximum tilt, so it could mean it would align east/west in the year 3275. 695, if used as feet is 6ft difference from 689 feet (a distance of 2m), it is possible that either the measurement is 212m or the angle could increase, making

Clendy Menhirs The Alignement de Clendy is a series of 45 menhirs on an archaeological site in Switzerland, which is located in Yverdon-les-Bains, a municipality in the district of Jura-Nord vaudois of the canton of Vaud. Charles de Sinner, an engineer, published a description of the site in 1896. He was then followed by Jacques Henri Gabas, who excavated the site in 1975. In 1986, the largest menhirs were returned to their original position defined from earlier digs while the smaller ones were replaced by concrete copies. Coordinates 46.780612,6.656602 The unique formation of the Clendy Menhirs is considered as the most important Neolithic site in Switzerland, situated on the shores of Lake Neuchâtel, the stones are thought to be erected more than 6000 years ago having been carved with human form. When the level of the upper Lake Neuchâtel decreased by 2.7 m after channelling the watercourses from the Jura (1869-1883), the menhirs appeared on the water surface in Clendy. In 1896

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. Coordinates 46.503224,6.684913   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 split

Arthur's Stone  Arthur's Stone in Herefordshire is a Neolithic chambered tomb, or Dolmen, dating from 3700 bc – 2700 bc. The capstone is said to weigh 25 tonnes with multiple support stones, and the Quoit Stone, which used to be a further stone towards the north, can be found towards the south. Due to tilt from Neolithic times, the monument would still have aligned north/south. Some tales suggest the tomb was built to mark the location of one of King Arthur's battles, while others tell that the stones were already present when Arthur slew a giant on the spot, who fell onto the stones and left indentations in one of them, which remain to this day. Coordinates 52.082315,-2.995271 Measurements If the path east/west is 8° then the path north/south is at 72°, and these two angles split the site into 80° and 100°. If a triangle whose sides are 13ft by 36ft at 100° fit over the site, then the following are correct. Area = 230.45ft Perimeter = 89.34ft It is possible that
