Above, this hillfort at Chankillo in Peru dating to 300 BC has a very distinctive ovaloid form and a length of about 990ft which is 900 Sumerian feet or 600 Sumerian cubits... or 360 Sumerian yards of 33.0"

Above, the hillfort at Chankillo in Peru has a breadth of approximately 770ft which is 700 Sumerian feet.

Above, this inner compound at the Chankillo hillfort has a diameter of about 165ft which is 100 Sumerian cubits of 19.8".

Above, this hillfort near SicaSica on the Bolivian altiplano has the same distinctive shape as the Chankillo hillfort and an identical length of about 990ft which is 900 Sumerian feet or 600 Sumerian cubits... or 360 Sumerian yards.

Above, the hillfort at SicaSica has a breadth of approximately 770ft which is 700 Sumerian feet, about the same as the site in Chankillo, Peru.

Above, 105 d and e oblique view showing remains of concentric rings near Viacha, Bolivian Altiplano. - At first it is difficut to tell whether the rings are remains of concentric irrigation channels or defensive works such as hill forts. The ring in the foreground could have been irrigation canal or part of hillfort, but the concentric rings in the background site are more similar to those of a hill fort.

Above, 105e this set of concentric rings looks like it would have had a good capacity for retaining water but the site has all the characteristics of a hillfort!

Above, the rings in the photo were two concentric terraces/pathways faced with walls on the outside.

Above, 105e the overall length of the site is about 1332ft which is 1200 Sumerian feet or 800 Sumerian cubits or 480 Sumerian yards.

Above, 105e the overall width is about 990ft which is 900 Sumerian feet or 600 Sumerian cubits or 360 Sumerian yards of 33.0".

Above, this site near the village of Chipaya can hardly be called a "hillfort" since it is in the middle of the vast Salar de Coipasa, yet it has similar characteristics to the "hillforts" of Chankillo and SicaSica, with the same ovaloid shape but is even larger being around 1760ft long which is 1600 Sumerian feet.

Above, the inner length of the site is about 1540ft long. which is 1400 Sumerian feet or double the breadth of the sites at SicaSica and Chankillo.

Above, the width of the Chipaya site is about 1320ft which is 1200 Sumerian feet or 800 sumerian cubits or 480 Sumerian yards.... the same as the length of the site at Viacha.

Above, oblique view of the site at Chipaya looking south towards the Salar de Coipasa.

Above, ground view of the site at Chipaya. It is occupied by a modern village who apparantly engaged contractors to build the ring wall around it, it is not known whether they followed an older route...

These sites such as Chankillo although sometimes described as hillforts, are also sometimes thought perhaps to have been observatories. The ovaloid shape is also reminiscent of the flattened circles and egg shapes found by prof A. Thom in "Megalithic sites in Britain". Prof Thom also put forward the use of the "megalithic yard" of 32.64" as the standard unit used in the construction of the stone circles and many were thought to have been designed using whole numbers and Pythagorean 3,4,5 triangles. We can note that the Chipaya formation when converted into Sumerian feet has an overall length of 1600 Sumerian feet for the outer ring and an overall width of 1200 Sumerian feet, which if contained in a rectangular box would have a diagonal by Pythagoras of 2,000 Sumerian feet with the rectangle also aligned to the solstices. In Sumerian yards of 33.0" the figures would be 480, 640 and 800 for the diagonal but the resolution of the imagery does not allow us to tell whether in fact Sumerian yards of 33.0" or megalithic yards of 32.64" were used, although Sumerian units are consistent with other sites found throughout the country.

Above, illustration showing how the site could be enclosed in a rectangle of 1600 x 1200 Sumerian cubits, aligned to the solstices and composed of 3,4.5 triangles. It is noticeable the width of the inner ovaloid ring is 1,000 Sumerian feet along the central axis of the solstice which would also be 400 Sumerian yards of 33.0" or 200 double yards of 100 Sumerian shusi - twice the length of the platform at Puma Punku in Tiwanaku.

Above, the little known megalithic ring at Wandlebury near Cambridge, England, also described as an iron age hillfort measures about 1054ft overall and is said to date to around 500BC. A large country house was at one time built within the grounds.

Above, the megalithic ring at Avebury in Wiltshire, England is so large that a village has been built within its banks. With an overall width of about 1374ft, it is said to be the largest henge type stone circle in Europe and to date to around 600BC. It is about the same size as the site at Chipaya, in Bolivia although circular instead of oval.

Above, this little known megalithic ring at Viacha in Bolivia has a diameter of around 3000ft, about three times larger than that at Avebury. Little is known about it. The inner ring has a diameter of about 1857ft. Within that there is a volcanic mound about 915ft in diameter in the centre which supports two apparantly man-made circular platforms carved from the natural rock, the central one about 117ft in diameter and the other about 110ft in diameter. The centremost cone or "pyramid" is said to have been covered at one time with stones, but these were removed and broken up as ballast for the nearby railway (same as happened with many of the ancient stones from Tiwanaku). The fortification walls seen on the west side were built at a later period and were used during the Battle of Ingavi when Bolivia was engaged in a war with Peru.

Above, this iron age hillfort at Caer Caradoc in Shropshire, England has a length of about 1100ft or 1,000 Sumerian feet.

Above, it has a breadth of about 660ft or 600 Sumerian feet which is 400 Sumerian cubits or 1 x furlong. The use of "Sumerian" cubits seems to have been a universal system both in ancient Sumeria, Europe and ancient America whilst the ditches and general size is similar in style to the site at Viacha in Bolivia

Above, this iron age hillfort at Maiden Castle in Dorset, England has a length of about 3300ft or 3,000 Sumerian feet or 2,000 Sumerian cubits or 5 furlongs which is also 10 "Atlantis stades" of 330ft (200cubits) or 20 "Atlantis stades" of 165ft (100 cubits) making it three times the size of the hillfort at Caer Caradoc and said to be the largest hillfort in Britain and Europe

The hillfort is said to date to 450BC and built on the site of a neolithic enclosure dating to 4,000BC. The length of 3300ft equates to 3,000 feet of 13.2 inches which is sometimes called a "Saxon" foot but is actually a "Sumerian" foot of 20 Sumerian "shusi" and we should note that if constructed in 450BC or earlier, then it was before the Saxons invaded and conquered England. The English furlong of 660ft is similarly in fact 600 Sumerian feet or 400 Sumerian cubits of 30 Sumerian "shusi". The length of the site comes out at a nice round number of 10 half-furlongs of 330ft which can also be considered as "Atlantis stades" since these stades of 330ft or 200 cubits also were used by Plato to descibe the rectangular plain in the Altiplano of Bolivia, whilst the quarter furlong of 165ft which is 100 Sumerian cubits was also used to describe the site of concentric rings at Pampa Aullagas on the Altiplano and this quarter furlong stade is the origin of several other units of measurement since 100 Sumerian cubits of 19.8" is also equal to 96 Egyptian Royal Cubits of 20.625" - useful for dividing parcels of land so that strips of land when subdivided come out in round numbers of cubits.

It is noticable also that describing the site as 20 "stades" of 100 cubits uses the number 20 so highly favoured by meso-American and early Tiwanku cultures and the discovery of "Sumerian" units of measurement throughout the ancient Americas suggests a world wide universal culture.
