The Stonehenge observatory, situated on the Salisbury plains of Southern England, remains one of the foremost mysteries of antiquity and there have been countless attempts to coax it into giving up its secrets.
For the most part, it has stubbornly retained them and the final, defeatist conclusion of many researchers, who came to do analytical battle, is that we will never truly know what the site was for.

Stonehenge is a very sophisticated standing stone circle, which contains the sum total of knowledge found upon the Great Pyramid, Khafre and Menkaure. Its pedigree is indelibly linked back to those magnificent structures.
Whoever built Stonehenge was utterly conversant with the age-old mathematical formulas, geodetic navigational systems, astronomical methodologies and measurement standards found upon the Giza Plateau of ancient Egypt.

With the mass exodus of pre-Dynastic inhabitants of Egypt, seeking more verdant homelands in Western Europe, their cherished knowledge migrated with them. In 3 locations of the Brittany heathland of France they erected rows of menhir standing stones, some huge (Er Grah...Le Grand Menhir Brisé...70 feet tall), and placed them in carefully coded positions.
One of these massive, ambitious undertakings occurred at Le Mènec (Carnac) where 1100 stones were placed in adjacent lines.
This site, along with those of Kerlescan and Kermario, would act as an eternal library of coded information for the newly arrived residents of Western Europe, throughout all of the generations to follow.

A short distance away, across the expanse of water known today as the English Channel, another ambitious project was initiated to erect the Stonehenge monument.
Suitable, durable bluestone was acquired from the Presely Hills in Dyfed, South Wales and shipped across the Severn Estuary to Wiltshire, Southern England. Additionally, in excess of 75 heavy sandstone blocks were fashioned in the vicinity of Marlborough, then, also, transported overland or by waterways to Wiltshire. Yet other types of stone were acquired from varied locations and trees were cut down to provide multiples of wooden posts.
With the final acquisition of all sought after materials the erection of, what would become, one of the great, lingering mysteries of all time commenced.

Conventional archaeological opinion accepts that the Stonehenge monument was built over a period of, perhaps, 1400 years beginning in 3000BC.
This conclusion appears to be largely based upon carbon dating of component post residues or antler digging tools and the like, found in the postholes. The posts, which were an integral and highly important part of the observatory, had a "use by" date and would rarely have lasted more than a century before requiring replacement. It's very likely that the archaeologists are getting mixed up about what constitutes a stage of development and what was, simply, ongoing maintenance.

The fact is that the Stonehenge site is a massive static computer and, for the most part, all components needed to be in place at pretty much the same time for the computer to work. There might have been a first stage that used bluestones and Aubrey Circle posts, but it's doubtful it would have persisted for very long. The Stonehenge monument was set up specifically to preserve the sophisticated knowledge that had been brought from the former homeland in Egypt. It was, therefore, important to build the site within a reasonable time-span and encrypt the ancient codes quickly, lest they slip from memory and be forgotten. Let's now start analysing the site ring by ring and component part by component part.

Figure 1: The blue circle is the Aubrey Circle, with a diameter of 288 feet. This diameter is exactly the intended, diagonal face length of the Menkaure Pyramid, from the base to the apex point. The distance (288 feet) is also ˝ of the 576 feet of diagonal face length from the base of the Great Pyramid to the height of the altar floor. The base perimeter of the Great Pyramid was exactly 288 reeds (of 10.5 feet each). The Giza Plateau was set out as a grid of 288 squares, each 189 feet X 189 feet (1/4th of the length of the Great Pyramid was 189 feet). The grid ran 18 squares east-west & 16 squares north-south. In Numbers chapter 7 of the Bible, Moses is given a total of 288 gifts. The Bible is packed with astronomical codes, which aspect is, oftimes, the sole preoccupation of an entire Biblical passage. Herodotus, the father of profane history, left us solid clues that the Pyramid acre was 28800 square feet. The Geomancer's mile of Great Britain was 57600 feet (28800 X 2). The Waitapu standing stone circle site in New Zealand was a dual, overlapping circle observatory, wherein the north-south extremities of the site extended through 288 feet, geometrically.

The Aubrey Circle represented the beginning point from which the rest of the Stonehenge observatory was mathematically conceived and 288 feet was the foundation number. All of the PHI circles and squares of Stonehenge were either a PHI ratio increase or PHI ratio reduction of the Aubrey Circle. Let's now introduce the other PHI circles in the series.

Figure 2: Once the Aubrey Circle (at 288 feet of diameter) was in place it was subjected to a PHI ratio increase to produce the next circle markers outward...288 feet X 1.6180339 (PHI) = 465.9937632 feet (466). It will be noted that this enlarged circle falls to the extremity of the majority of the Stonehenge site. However, it is clearly marked by 2 components on the Avenue. This code alludes, in part or symbolically, to the 46.5 pyr. acre figure found on the Khafre Pyramid, which was dedicated to 1/4th of the 18.613- year lunar nutation cycle. The 466 figure crops up as an important part of the PHI progression (based upon 288) in some artefacts, like the 3rd increment of a Dynastic Egyptian Royal Cubit. It is also a part of the PHI coded measurements found at the Crosshouse of Miringa te Kakara in New Zealand (ref. Articles 4 to 5 of this website). This circle diameter was extremely important in that it was exactly 172.8 Megalithic Yards (of 32.360678 inches each). The Great Pyramid perimeter value was 1728 Royal Cubits (of 21 inches each); Silbury Hill was intended to code a circumference of 1728 feet; The outer rim circumference of the Sarsen Circle was 345.6 feet, which is 172.8 X 2; The Crosshouse at Miringa te Kakara in New Zealand worked to a circumference of 172.8 feet. The huge standing stone row site of Le Mènec worked on the basis of 1728 Megalithic Yards. The 1728 code related primarily to world navigation, using a sexagesimal circumference code in conjunction with a "league" diameter code.

Figure 3: The 3rd segment of this Dynastic Egyptian Royal Cubit codes 4.66 inches in the diameter of a circle generated from the bottom left corner of the rod. Note how the 1st segment codes PHI & the 2nd segment codes PI. These rods were, primarily, for mnemonic reference to the size of the Earth in their full lengths. Any trades person would quickly discover that the rod, here shown, couldn't be utilised as a measuring rod in construction work, as the individual segments are not in ratio with each other. The totality of the rod appears to be a memory device, related to the most important numbers of antiquity.

The 466 feet diameter circle was directly related to the size of the Earth under its PHI geodetic assignment. Remember, the formula for determining the "ring of the Earth" was to take the vertical height of the Great Pyramid, according to its PHI assignment of 168 Megalithic Yards (453.049492 feet) and divide this value by ˝ the length of the top altar floor (22 feet...full length = 44 feet). The result was 453.049492 ÷ 22 = 20.59315873 (this value read in inches was the length of the "PHI-coded" Dynastic Egyptian Cubit. This length was then multiplied by 1200...(20.59315873 X 1200) = 24,711.79047 (read as miles of 5280 feet each to describe the "ring of the Earth" under the PHI geodetic system). The diameter of this Stonehenge circle represents, therefore, 1/280,000th of the ring of the Earth. Let's test this concept mathematically:

1. The Aubrey Circle is 288 feet in diameter and this larger circle is a PHI (1.6180339) increase on that diameter, which means...288 X PHI = 465.9937632 feet or exactly 172.8 Megalithic Yards of 32.360678 inches each.

2. The PHI assigned value of the "ring of the Earth" was 24,711.79047 miles or 130478253.7 feet. This "ring of the Earth" value, ÷ 465.9937632 = 280,000. Similarly, the Megalithic Yard value for the PHI "ring of the Earth" was 48384000 MY, with the 172.8 MY diameter of this Stonehenge circle representing 1/280,000th of that value.

3. The 130478253.7 feet (24,711.79047 miles), when divided by 288 feet (the diameter of the Aubrey Circle) = 453049.492 feet. The PHI assigned, literal height of the Great Pyramid was 453.049492 feet.

Figure 4: The Stonehenge site magnified, showing parts of the Aubrey Circle, then "Y" Holes and the Sarsen Circle ring further in. It is important to realise, at this juncture, that the post and component positions were based on these perfect, concentric, PHI reducing circles, but then custom placed according to the dictates of 3,4,5 triangulation or other specialised coding. The Sarsen Circle, for example, was made very marginally elliptical to code 1 second of arc of the "ring of the Earth" under the sexagesimal geodetic system. But let's concentrate on "Y" Holes for the moment.

The way "Y" Holes was configured, was to reduce the 288 feet Aubrey Circle diameter by PHI to achieve a diameter of 177.9937985 feet (178 feet). This is exactly ˝ of the base length of the MenKaure Pyramid under its PHI assignment of 356 feet. Its other assignments were 356.4 feet (fathoms or "rounded" Megalithic Yards) and 357 feet (Sabbatical Calendar system). In a sense, this "Y" Holes PHI circle inferred all 3 codes simultaneously. Let's explore how "Y" Holes was calibrated to code the size of the Earth:

1. The diameter of "Y" Holes was, essentially, 66 Megalithic Yards of 32.360678 inches each. This diameter multiplied by a slightly adjusted PI value (3.141818182...1728 ÷ 550) = 207.36 MY. This number is a part of a very important numerical progression, based upon a "rounded" PHI value of 1.62, which goes: 1.62, 3.24, 6.48, 12.96 (˝ the duration of the Precession of the Equinoxes was 12960 years), 25.92 (Precession endured through 25920 years), 51.84 (the degree angle of the Great Pyramid's diagonal faces and a major number for geodetic calibration when navigating in leagues…16500 feet X 3.141818182 = 518400 feet), 103.68, 207.36 etc.

2. If the 207.36 MY circle were divided up into 12 equal parts, then each segment would be 17.28 MY, again demonstrating the much used 1728 code.

3. It seems apparent that there was a 4th type of Dynastic Egyptian Royal Cubit that was exactly 1.728 feet in length or 20.736 inches. It's quite plausible to assume that the Greek "Stadia" measurement was originally designed to be 1/207360th of the size of the Earth, under the Great Pyramid's sexagesimal geodetic system.

4. In Olympia, Greece, where the Olympic games were held, the main event was a foot race of 600 Greek feet or one stadia. The course has a starting line and a finishing line, both cut into solid rock. The distance between the lines, existing to this day, is 192.28 metres (630.83985 feet). It is very coincidental that this length falls so close to 630 feet (60 reeds, 360 Royal Cubits, 420 common cubits, 7560 inches). Under this calibration, using the Great Pyramid's perimeter value as the geodetic increment, the Earth's size would be 130636800 feet ÷ 630 feet (1 stadia) = 207360 stadia to circumnavigate the world. The probability is that the Greek Stadia measurement had become slightly corrupted by the time it was incised into the rock at Olympia. It is obviously based upon an earlier, perfect standard found within the Great Pyramid's sexagesimal geodetic system.

5. The "Y" Holes Circle had other dynamic attributes, including an affiliation to Menkaure Pyramid's base length in the "Y" holes diameter, as well as representing the PHI calibration circle for Stonehenge's Holy of Holies calculation matrix. These attributes included other, marginally different interpretations of diameter. It's altogether possible that the Menkaure Pyramid was built to a "fathom" increment of 5.5 feet and was 259.2 fathoms in circumference. This would have meant a base side value of 356.4 feet per side and the official measurement is 356.5 feet. "Y" Holes at Stonehenge was configured to represent ˝ of Menkaure's base length under standard, "11 series" or PHI assignments. Another way of viewing the diameter of "Y" Holes is as 32.4 fathoms or 178.2 feet. This distance would be 1/8th of the perimeter value of the Menkaure Pyramid under its fathom assignment. It could also be interpreted as 178.5 feet and relate to the Sabbatical calendar system encrypted into Menkaure Pyramid.

The "Z" Holes Circle, immediately inward from "Y" Holes was a non-PHI, customised circle, the attributes of which are directly related to the sexagesimal/ septimal geodetic system for measuring the "ring of the Earth".
The intended diameter of "Z Holes" was exactly 132 feet (1/40th of a mile). It will be remembered that the altar atop the Great Pyramid would have been geometrically configured to be 44 feet in length and 3 feet higher than its circumnavigating terrace, set at a height of 450 feet. This means that each outer face of the altar was 132 square feet, for a total of 528 for all 4 sides (coding the 5280 feet in the mile).
Alternatively, the altar would have included 2 geodetic, Earth navigational systems in its floor surface geometry. One circle, based upon a 44 feet diameter and marginally adjusted rendition of PI, produced a sexagesimal rim calibration of 138.24 feet. The rim was used for determining degree angles when working in linear (diameter) increments based upon "11 series" measurements (leagues, miles, furlongs, chains, rods/ perches, fathoms and links). Atop the pyramid, principles of navigation, based upon ocean traversals measured and plotted in leagues or breakdowns of leagues were taught in reference to this circle.
Another circle of 42 feet diameter produced a circumference of 132 feet (with a marginally adjusted rendition of PI). The 132 feet circumference circle on the Great Pyramid's altar was intended to convey 1/99000th of the ring of the Earth under its 11 series (league) geodetic assignment. The Menkaure Pyramid (under its PHI assignment) was 132 Megalithic Yards in length or 528 MY for a full perimeter circumnavigation.

The 132 number, therefore, occurs profusely in ancient geodetic endeavour. The way it was used on "Z Holes" was both in its diameter and, by consequence, circumference values. The diameter @ 132 feet represented 1/990000th of the ring of the Earth under the 24750 mile "11 series" assignment (the same length fraction as occurring on the Great Pyramid). It is also encrypted for mnemonic reference into the 9th segment of the Dynastic Royal Cubit shown above.
With the use of the "geodetic" rendition of PI at 3.141818182 (1728 ? 550) the circumference aspect of "Z" Holes was intended to be 414.72 feet (207.36 X 2). This circuit was intended to convey 1/315000th of the "ring of the Earth" under the sexagesimal/ septimal system…or 13.824 inches per degree of arc (note: the 44 feet diameter circle atop the Great Pyramid worked to a circumference of 138.24 feet…51.84 inches X 32 or 11.52 feet X 12).
The 414.72 feet in this circuit was also 17.28 inches X 288, 51.84 inches X 96 or 11.52 inches X 432.

Figure 5: "Z Holes" (a customised, non-PHI circle), is marked by a red circle. Further inward, the inner rim of the Sarsen Circle is also marked red, as this was a non-PHI related circuit as well. Component post or stone positions within these "perfect" circle renditions are seen to meander offline. This is due to a need to place them according to the dictates of 3,4,5 triangulation, which aspect will be demonstrated as we proceed.

We now move inward to the magnificent Sarsen Circle.
