The Cyclopean Cities of Ancient Latium
The Cyclopean Cities of Ancient Latium
The countryside around Rome is littered with relics of a past more or less remote. One feels almost a continuity there between the ancient and the modern world, with the ancient Roman ruins being almost a familiar presence as if part of the natural landscape. Yet, one also finds there remains of a much older and mysterious past. Massive cyclopean walls encircle towns and villages, their stones darkened by the passing of centuries and millennia. One can never get used to them, so strange they are in their interlocking geometries and so different from the familiar contours of Roman and Medieval walls. They loom as a relic from an entirely different past of which we know almost nothing.

Who built the cyclopean walls and why?
The small towns of Sutri, Amelia, Pelastrina, Alatri, Ferentino, Segni, Sezze, Veroli and Arpino, all in the Province of Frosinone, Norba, Cori and Circei, Cortona, Cuma in the Province of Latina, Amelia in nearby Umbria, as far as Ansedonia, Orbetello and Roselle in Tuscany and Alba Fucens in Abruzzo, are entirely surrounded by cyclopean walls that survive to this day in varying states of preservation.
They loom even to this day over 15 meters high on the Acropolis of Alatri, and are almost intact over their entire circuit around Ferentino, Segni and Norba.
The stones composing the walls are truly gigantic, each weighting many tons, and as finely fitted together as to leave a few millimeters at most between the joints. But it is their near impossible acute angles and interlocking corners that cause the greatest amazement, as if each stone was individually carved to be a piece of a gigantic jigsaw puzzle.

Scauri (Pirae) South Lazio
Another coastal head point, like Circeio, Terracina and next one Scauri, obviously also had megalithic blocks. Remains of a harbour of polygonic blocks can be seen.
The name of this resort area, in which during the summertime holds almost 70 thousand people, has its origin from Marco Emilio Scauro, consul and Princeps Senatus in 115 BC, who owned a luxurious maritima villa at the port of Pirae (this was the first name of the area).
Of the ancient city of Ausone origin, which along with Minturnae made up part of the “Pentapoli Aurunca”, one can today admire part of the polygonal city-walls in blocks of limestone (the “Megalithic Walls”)

The interesting part is that it seems the flat outer surface was made AFTER the wall was put together. I also seen such things at Norba.

Not much has changed since the time when Ferdinand Gregorovius first described the cyclopean walls of the Acropolis of Alatri as “the most astounding monument of the past in Latium”. It was 1859 when he wrote these words:
“The sight of this marvelous masonry, which equals in size any existing Egyptian building, would amply repay the visitor for the longest and most fatiguing day’s journey […] When I walked round this black, Titanic, construction, just in as good preservation now as if years, instead of thousands of years, had passed over them, I was filled with amazement greater than when I first beheld the Colosseum at Rome”. 
In over 150 years, very little has changed also in our knowledge of the builders and purpose of these cyclopean structures. The debate on the original builders of Alatri and the cyclopean walls of Latium raged for much of the 19th and the 20th Century. Lacking any other plausible explanation, the construction of the walls was attributed to the Romans of the early Republican period (III – I Century BC) and the whole question was put to rest for almost half a century. Indeed, no other civilization known to historians and archeologists would have had the technical skills and social organization to afford the construction of the miles long walls and to move tens of thousands of stones, some of which weighting in excess of 27 tons.
San Felice Circeo
Below images are from a book from 1850. It shows a circular tomb, that I can not find on any modern video or publication, suposedly on mount Circeo. The top gate shown is Arpino)
It also shows an acropolis structure on mount circeo, which is due to the vegetation hardly vissible or discenable in modern times to compare how accurate this image is.
I knew about the wall in Circeo, from earlier pics and JJ and Hugh been there. But I never heard about the megalithic structures and tholos beehive tomb or temple on Mount Circeo. I have not seen any publications or modern YouTube videos on this besides this 1850 gravure. It’s reasonably significant and seemingly nice structures as that would strengthen a Greek Mycenea link. I would love to go inside to check it out.

‘Upon the east end of the promontory ridge are the remains of an enceinte, a polygonal structure that roughly forms a rectangle and that measures about 200 by 100 metres. The blocks are very carefully cut and jointed; right angles were intentionally avoided. The wall stands almost entirely free, as at Arpinum – polygonal walls in Italy typically form embanking walls – and increases considerably in thickness as it descends. The blocks of the inner face are much less carefully worked both here and at Arpinum. It seems to have been an acropolis, and contains no traces of buildings,
Except for a subterranean cistern, circular, with a beehive roof of converging blocks.
The modern village of San Felice Circeo seems to occupy the site of the ancient town, the citadel of which stood on the mountain top; its medieval walls rest upon ancient walls of Cyclopean work of less careful construction than those of the citadel, and enclose an area that measures 200 by 150 metres (660 by 490 ft)’
|The stepped megalithic Hyeron (altar) on the Acropolis of Segni, also sorrounded by massive cyclopean walls, is a good examples of how the altar on the Acropolis of Alatri would have looked like before the Medieval cathedral was built on top of the older sanctuary. Also at Segni a church was built on top of the original Hyeron, partly reusing the walls of a Roman temple to the Goddess Juno Moneta – Photo by Author|

We see also the similar megalithic sites in Greece, attributed to the Myceaneans. But really, the Illyrians or Pelasgians where all over the Mediterranean.
I have allways said the myceneans and walls around the acropolis in Athens are identical to the Italian sites and also pelasgian/illyrian.
During my own visit to Mycenea I only drove past Tiryns and did not have time to visit the pyramids structures. I have to go back there.

|Kastraki or Citadel of Ancient Assini, next to Tolo. From the 5th millennium BC up to about 600 AC, the citadel was continuously inhabited, but the first citation to Assini was made by Homer (B 560), indicating that Argos , Tiryns , Epidaurus and other cities of Argolida participated in the Trojan war with a large number of ships ( eighty ships) .

Cadmus and Harmonia
In Greek mythology, Cadmus (/ˈkædməs/; Greek: Κάδμος Kadmos), was the founder and first king of Thebes. Cadmus was the first Greek hero and, alongside Perseus and Bellerophon, the greatest hero and slayer of monsters before the days of Heracles.
and was important long before the greek civilization.
The Scamander had as son Teucer, his daughter, Batia married Dardanus [the Dardanians were an Illyrian tribe], which came from Samothrace and founded Troy. The grandson of Dardanus was Tros, which had as son Ilus II (which re-founded Troy and gave his own name to the city). Ilus’ son was Laomedon, and Laomedon’s son was Priam. The father and the son of this king, Paris, will be defeated by the Greeks after raping Hellen (action that humiliated the Greeks and menaced since he would have inherited Hellen’s kingdom).

One of these hilltop fortified settlements is Purkin Kuk, set on a hill to the south of Stari Grad.
“Stari Grad was originally named Faros (Greek: Φάρος) by the Greek settlers from the island of Paros, who arrived in 384 BC. It is thought that the name may come from the previous inhabitants of the area. A great naval battle was recorded a year after the establishment of Pharos colony by a Greek inscription in Pharos (384 – 383 BC) and by the Greek historian Diodorus Siculus (80 – 29 BC), initiated by conflicts between the Greek colonists and the indigenous Hvar islanders, the Liburnians, who asked their compatriots for support. 10,000 Liburnians sailed out from their capital Idassa (Zadar), led by the Iadasinoi (people of Zadar), and laid siege to Pharos. The Syracusan fleet positioned in Issa was informed in time, and Greek triremes attacked the siege fleet, taking victory in the end. According to Diodorus, the Greeks killed more than 5,000 and captured 2,000 prisoners, ran down or captured their ships, and burned their weapons in dedication to their gods.
This battle meant the loss of the most important strategic Liburnian positions in the centre of the Adriatic, resulting in their final retreat to their main ethnic region, Liburnia, and their complete departure from the Italic coast, apart from Truentum. In Roman times, the town became known as Faria, which was turned into Hvar by the incoming Slav population. When the administrative capital of the island was moved to today’s Hvar town on the south coast, the old town became simply known as Stari Grad. (“Stari” translates as “old” and “grad” as “city” in Croatian.)”
It’s 276 metres above sea level, with superb views of the surrounding area. The stone mound is one of the largest on the island, and may have had some ritual significance, in addition to clearing the land for cultivation. Dating from around the first millenium B.C., it was possibly associated with an ancient settlement at Stari Grad, and the nearby agricultural land.. At the same time, there were several other larger hilltop settlements, such as at nearby Gračišće, and also on the site of today’s fortress above Hvar.
Terni “pyramids” italy”
In recent years, aerial satellites have discovered hills across Italy that are shaped like four cornered pyramids suggesting that these are no ordinary hills but the sites of ancient man made constructions beneath the earth’s surface!
These fascinating hill pyramids can be seen at Santa Agata de Goti near Naples where there are three of them. There’s one at Versallo near Reggio Emilia and two monumental hill pyramids at Piediluco near Terni, one hundred kilometres north of Rome. We have an interesting article detailing the three hill pyramids at Pontassieve near Florence that’s well worth a look. Another unusual common trait that these sites share is that they’re all located along the Italian parallel of the ‘Zeus Line’. This line comes from a legend that the Greek lord of the gods, Zeus used to fly directly along a route from Mount Olympus in Greece to the Hyperboreans.
Other such parallels of the Zeus Line that runs through other countries sees lots of other pyramid hills like this and unusual monuments.
Yet, whoever visits the little town of Ferentino, still encircled by its beautiful cyclopean walls, would immediately realize that this attribution is plain nonsense. Here one sees more than in any other place three distinct and clearly recognizable stages of construction: the cyclopean, the Roman and the medieval. The inscription of the Roman censors Aulus Lollius and Marcus Irtius still stands to commemorate the restoration of the walls by the two censors in 180 BC. Of course, the restoration was made with relatively small, square blocks of stone upon the already ruined cyclopean masonry underneath, which served as a 10 meters high foundation for the new roman wall. Even without the inscription, no reasonable person would ever think that the cyclopean masonry and the brick-like stone wall above could belong to the same period, not to mention having been built by the same people! Yet one still reads in guidebooks and even scholarly studies that the two censors built the whole of the walls of Ferentino, including the cyclopean portion.

Nor did the Romans ever claim authorship of such a feat as building the walls of Alatri, Norba, Segni or any other of the cyclopean cities of Latium. Quite to the contrary, ancient historians had a tendency to attribute these structures, so similar to the great walls of Tiryns and Mycenae, to mythical ancestors like the Pelasgians.
If then the walls were not built by the Romans, who built them? More recent scholarship has shown greater openness towards the idea of a pre-Roman date for the cyclopean walls. The pre-roman peoples of the Hernici and the Volsci are therefore sometimes credited for the construction of the walls. Yet, also this attribution, though much more plausible, appears to rest on very thin evidence. The Hernici formed a league as far back as 495 BC, until their capital, Anagni, was taken by the Romans in 306 BC. Yet one is surprised not to find even the slightest trace of cyclopean walls in Anagni itself, where the walls – which are with good certainty attributed to the Hernici – are rather built with much smaller square blocks.
Even the ultimate function of the cyclopean walls and acropolises is ultimately shrouded in mystery. Of course, the immediate thought that comes to mind when seeing a wall is that it might serve some defensive function. Yet, in spite of their grand scale, cyclopean walls would offer very little protection and certainly no better protection than a much more simple structure built of bricks or even wood. Not only are the walls pierced by several gates and lacking towers or any other defensive feature one would expect from a fortification of comparable size, but they even present features that seem to exclude any meaningful defensive function. The author Giulio Magli lists several of this features in his book “I Segreti delle Antiche Città Megalitiche” [Secrets of the Ancient Megalithic Cities]. For instance, the acropolis of Circei lacks any defense on the Northern side, which was therefore entirely open and defenseless towards the mountain. Even the main gate of Norba is too broad, at over 7 meters, to allow any kind of covering unless we imagine a capstone of truly monstrous size as could have never been supported by the side walls (there is ample evidence the builders of the cyclopean walls didn’t know the principles of the arch, or deliberately chose not to use it in their constructions) . These cyclopean walls are much more similar to a sacred precinct, like the themenos of a temple, than to a fortress of any kind.
|The Main Gate (Porta Maggiore) to the ancient city of Norba. Over 7 meters wide, the gate is flanked by a round “tower” to the right of unclear function, which is a masterpiece of polygonal megalithic architecture – Photo by Author|
|Another gate in the walls of Norba, facing the cliff, and sormounted by a huge architrave. Also note the very fine texture of the polygonal blocks, each one of which weighting many tons – Photo by Author|
This is especially true in the case of the Acropolis of Alatri, undoubtedly the finest of its kind in Italy and among the greatest megalithic realizations in the Mediterranean. Other than the usual absence of any defensive features inside or outside the perimeter of the Acropolis, the only structure inside the precinct of its walls appears to be a large stepped platform. Here is found some of the finest cyclopean masonry in Italy and probably in the world, including a stone with over 15 angles, with joints so tight that they don’t allow even the finest blade to pass between two stones. This platform, called a Hyeron, was clearly an altar of some sort, and is moreover very carefully astronomically and geometrically aligned as to be the virtual center or omphalos of the whole city of Alatri.
Recent research has shown that the entire city of Alatri was designed after a roughly circular plan, with three concentric walls converging towards the Acropolis. The gates defined a number of axes which show evidence of having been carefully astronomically aligned towards the rising and setting of the Sun at the solstices and equinoxes. A number of stellar alignments also seem to point to the constellation of Gemini, Orion and the Southern Cross, at a time when it was still visible above the horizon in the Northern hemisphere. Also, the golden section was embedded in the design of the Acropolis and its gates.
The stars may shed new light on the age-old question of the dating of the Acropolis of Alatri: A recent archaeo-astronomical study shows that the Acropolis could not have been built later than 1,270 BC, when the main axis of the city and of the Eastern wall of the Acropolis was aligned to the star Polaris, with the North-West wall aligned to the rising of the Sun on the morning of the Summer equinox and its setting on the Winter solstice. The same study found evidence of an astronomical clock based on the shadow projected by the sun along the tunnel formed by the lesser gate of the Acropolis, also pointing at a date in the XIII Century BC. 
Previous studies had already shown that the shape of the Acropolis almost exactly mirrors the profile of the constellation of Gemini. Even on a grander scale, the position of the towns of Alatri, Atina, Arpino, Anagni and Ferentino (ancient Antinum) matches the same profile of the constellation of Gemini (or, according to other interpretations that also include several other centers of Lower Latium, the constellation Ursa Maior). 
According to tradition, these five cities were founded by a legendary king Saturn (sometimes identified with the God of the same name) and are therefore called “Saturnian Cities”. According to the same legend, the tomb of Saturn was located in the town of Atina, which is also surrounded by imposing cyclopean walls of unknown date.
Following the renewed interest in the megalithic civilization of Central Italy, even UNESCO has taken an interest in the astronomic alignments of the acropolis of Alatri. 
Even UNESCO now acknowledges that the cyclopean walls of Lower Latium may be indeed several centuries older than their assumed dating to the Roman period, and laments the lack of a reliable stratigraphy that may shed more light on their true age. UNESCO defines Alatri as “the most spectacular example of the use of geometry and astronomy in planning” and is considering its inscription as a World Heritage site.
