Caral is an important site in the Supe Valley of central Peru near the coast and was part of the Norte Chico civilisation. It was occupied during the third millennium BC, although some push that back as far as the fourth millennium. Caral is claimed to be the oldest urban settlement in the Americas(a), although other sites in the region may challenge that.>Arthur D. Faram has written a petroglyphic study of Caral(c).<
The 600 hectare site includes a pyramid complex that may have preceded those of the Egyptians. An early quipu was also found at the site suggesting some form of continuity with the later Inca civilisation.
In the 1950’s, further south, in the Manchay Valley near the capital Lima, Karola Siebert was convinced that she had found Atlantean remains, while further south again, over the border in Bolivia we have Jim Allen’s chosen location for Atlantis near Lake Poopó.
A French website(b) has on offer the strange idea that the longitude of Caral in Peru and that of Xian in China and their respective relationships with the Prime Meridian at Greenwich and the longitude of Giza have some bearing on the location of Atlantis, which the author, Fabien Pardo, places in the Antarctic!
I reject all South American locations as possibly Atlantean and do so principally because the idea of an attack on Athens being launched from the west coast of South America, thousands of years ago, is, to put it kindly, just silly. However, it is quite clear that this region has had a fascinating prehistory and should keep archaeologists busy for generations to come.
Lake Titicaca is the largest lake in South America and at over three kilometres is arguably the highest navigable lake in the world**, shared by Peru and Bolivia. In spite of claims to the contrary it is a fresh water lake, but is slowly reducing in size due reduced inflow from the retreating Andean glaciers. Lake Poopó to the south has now dried out completely(a).
***Karakul in Tajikistan exists at 4,000 metres and “is so salty, it’s almost impossible to navigate a boat on it without capsizing due to the vessel riding so far out of the water.”(e)*
To the south of the lake are remarkable archaeological remains of Tiwanaku and the equally exciting Puma Punku. Both sites have produced some extreme theories regarding the builders of these monuments, their technology level and the date of their construction. Arthur Posnansky, followed by Kurt Bilau have proposed a date of circa 9500 BC as the date of fall of Tiwanaku. There are also reports of pre-Incan structures submerged in Titicaca(d) .
South of Lake Titicaca, near Lake Poopó is Pampa Aullagus, a site identified by Jim Allen as the location of Plato’s Atlantis. While there is little doubt that advanced cultures existed around Titicaca, linking the region to Plato’s story is stretching credibility to its limits. I have already argued in respect of Jim Allen’s Andean theory, that the idea of an invasion of the eastern Mediterranean by an army from the west side of South America is untenable. That they would try it in reed boats like those of Titicaca is equally daft. Then, that this mighty army from ten regions of South America were defeated by the small city-state of Athens is just as laughable.
Equally questionable is the idea that there was a Sumerian presence around Titicaca, in relation to which Clyde Winters quotes(b) James Bailey as well as Ruth and A. Hyatt Verrill in supporting the idea that Lake Manu in Sumerian tradition was in fact Titicaca. The controversial(c) Fuente Magna bowl is also offered as evidence of this idea.
Tiwanaku (Tiahuanaco) is an ancient city whose remains are located over two miles above sea level near the southern end of Lake Titicaca on the Altiplano of Bolivia. It was first encountered by Spanish conquistadors in 1549. Tiwanaku has all the features of a harbour, which has led some to describe it as the seaport of nearby Puma Punku another remarkable ancient site(o).
The ruins are scattered over a number of square miles through which the Guayqui-La Paz railway was constructed, which was responsible for the breaking up of many monuments to provide ballast. Prior to that, stone from the site was used in the construction of nearby homes and a church.
Belisario Díaz Romero believed that Tiwanaku had been built by a race of people he calls Homo atlanticus, who had come to America from Atlantis over a landbridge from the east, outlined in his 1906 book Tiahuanacu. Heather Pringle notes(t) that before Romero, “Francis de Castelnau (1810-1880), for example, proposed in the mid-19th century that Tiwanaku was the work of wandering Egyptian pharaohs, as opposed to the ‘imbicilic race that inhabits the country today’.”
The controversial Arthur Posnansky, who linked Tiahuanaco with Aztlan, the mythical “white” island homeland of the Aztecs investigated them in the early 20th century. The similarity of Aztlan with the name of Plato’s city has excited some straw clutching Atlantis seekers into claiming a definite connection between the two.
Posnansky also noted that the expected alignments of structures at Tiwanaku were offset by an amount that suggested their construction at a time when they would have been correctly aligned with respect to the cardinal points. He, after many years of study, was convinced that Tiahuanaco was the oldest civilisation on Earth  dating it to around 15,000 BC. Although, as you can see below, Posnansky’s work and particularly his dating of Tiwanaku has been rejected by many, he still has supporters. In Graham Hancock‘s 1995 book Fingerprints of the Gods , he supported Posnansky’s date, referring to his work throughout the book. Ian Alex Blease, a devout sceptic took issue with this endorsement (aa). For my part, I note that Hancock was happy to support Posnansky in ‘Fingerprints’, but in America Before , in spite of its title, he gives Posnansky’s date no mention, perhaps because it clashed with his new date for the destruction of his ‘Lost Civilisation’!
Charles Orser Jnr. debunked Posnansky’s dating in a 2001 article(k) as did Paul Heinrich(n). However, R. Cedric Leonard believes that Posnansky’s date addressed all of the mysteries associated with the site and “Thus I think it likely that Tiahuanaco was built at sea level c.15,000 B.C. as an Atlantean port.”(z)
Some researchers, including Jim Allen, have studied Tiwanaku’s remarkable Gate of the Sun and identified the figures carved on it as a sophisticated calendar(v). Ashley Cowie has recently proposed that Tiwanaku was located on an ancient Prime Meridian(w).>A paper published on the Researchgate website offers a study of the mathematics of Tiwanaku’s Gate Of the Sun(ac).<
In the 1920s, Edmund Kiss studied the ruins of Tiwanaku and concluded that it had been constructed by Nordic refugees from Atlantis which had been destroyed by a falling moon! His ideas were enthusiastically received back in Nazi Germany. A further expedition was planned but never materialised because of the start of World War II.(u)
In sharp contrast, is the claim(l) by Roger Elefant that later construction at Tiwanaku was carried out by the Vikings!
However, a more recent, but catastrophic, explanation is offered by Stephen Smith(d) on the Thunderbolts.info website. Perhaps Smith’s ideas might be combined with the studies of George Dodwell to produce a more comprehensive hypothesis. Posnansky’s date is greatly at variance with conventional dating that puts the flourishing of Tiwanaku at 1200 BC until 1200 AD. The latter part of that period roughly coincides with the existence of the Wari Empire, a possible rival of Tiwanaku(e).
.A number of claims attempting to link Tiahuanaco with Atlantis have been made, with one anonymous blog(y) insisting that it was the capital of Atlantis. James Bailey was an early advocate  of a Peruvian Atlantis with its capital at Tiwanaku or Chan Chan, which was probably the largest pre-Colombian city in South America.
The claim of a direct connection between Tiahuanaco and Atlantis is hard to accept on a number of grounds; for example, the idea of an army travelling from the west coast of South America to attack Greece in the east of the Mediterranean is not tenable. That there was an advanced culture in the Andes is undeniable but to link it to Plato’s story is stretching credibility to extremes. Lake Titicaca and Tiahuanaco have plenty of mysteries still to be explained. In 1980 the Bolivian scholar, Hugo Boero Rojo, aided by one of the local natives, Elias Mamani, located underwater ruins off the coast of Puerta Acosta. His discoveries included megalithic temples, flights of stairs and stone roads.
More recently, Dave Truman has written about an alignment known as ‘The Way of Viracocha’ that runs from Cajamarca in the north, through Cuzco and Tiwanaku and finishing at Pukara Grande(p), oriented exactly 45° west of true north. Truman has built on the work of Maria Sholten d’Ebneth (1926-2007), who wrote of the La Ruta de Wiracocha in the 1970’s(q). Others have expanded on her work, but usually in Spanish. Truman has speculated on whether “Viracocha, the great teacher and restorer of civilisation in the Andes, in some way embodied the scientific knowledge of a sophisticated, but long forgotten high culture?” Truman
also discusses the ‘chakana’ or Andean stepped cross and it possible meaning.
It was reported in October 2013(g) (that a team of Belgian and Bolivian archaeologists had found an assortment of ceramics, gems and gold objects at an apparent ceremonial site beneath the waters of Lake Titicaca, which was sacred for the Incas and Tiwanakus. It was not until 2019 that images of some of the artefacts recovered from the lake were widely published(x).
We cannot leave the matter of mysterious Tiahuanaco without referring to the fact that some miles further south is Lake Poopó beside which Jim Allen is convinced that the city of Atlantis was located. Allen claims that the large plain to the west of the lake is the plain mentioned by Plato as being adjacent to the city of Atlantis. In a recent documentary “Atlantis in the Andes” broadcast by ‘Discovery Civilization’, Allen identified Tiahuanaco as one of the ten kingdoms of Atlantis. However, I cannot help noticing that while Tiwanaku, claimed to be 17,000 years old, provides us with an astonishing wealth of structures, Allen’s chosen Atlantis site, Pampa Aullagas, offers little more than rubble!
Another supporter of an Andean Atlantis is Sean Bambrough, who has been developing a theory since 1999 that identifies Tiwanaku as the city of Atlantis(h). In February 2015, Marcelo Ozorio also suggested a link with Plato’s Atlantis and most interesting is the huge number of images included on his site(i). There is also a large collection of related images on a YouTube clip(m).
In 2008, David E. Flynn brought to public attention an astonishing series of satellite photos(a) that show a vast network of the remains apparently of human structures that extend for many miles around Lake Titicaca. These ‘geoglyphs’ encompass Tiahuanaco.
The most remarkable collection of early photos of the Tiwanku site can be found on the Above Top Secret website(b). The accompanying text makes a strong case for treating the location as archaeologically contaminated and as a consequence that many of the dates proposed for the site should be considered suspect. Other mysteries are the fact that saltwater Lake Titicaca contains known sea life and that old waterlines are slanted(c).
In late March 2015, the Bolivian government announced(j) that ground-penetrating radar had identified what appeared to be a buried pyramid in the Tiwanaku complex as well as other ‘anomalies’ and that excavations may start in May or June.
A mixed Spanish and English website(f) offers a number of interesting papers including a chapter from Posnansky’s book Tiahuanaco: The Cradle of American Man.
Archaeology magazine has an interesting Q & A paper relating to the history and current state of preservation at the Tiwanaku site(s).
A May 2017 report(r) confirmed that the entire Tiwanaku complex is much more extensive than previously thought, covering an area of at least 650 hectares (1,675 acres).

Lake Poopó in the Bolivian Andes is adjacent to a large plain that is claimed, by Jim Allen, to be the site of Atlantis. Allen has reduced Plato’s dimensions by half as he contends that originally the South Americans counted with a base of twenty rather than our base of ten. With this arbitrary reduction he found that Plato’s plain of Atlantis could be identified with the plain to the west of Lake Poopó. Allen names the exact site of Atlantis itself as Pampa Aullagas.
Unfortunately, by 2015, Poopó, Bolivia’s second largest lake had been reduced to a salt pan and Titicaca, the largest, was also in trouble(a).

David Antelo Justiano (1971- ) is a Bolivian engineer who has identified a plain in the Beni region of Bolivia, north-east of La Paz, as that referred to by Plato as being adjacent to Atlantis. Antelo has posted a video on YouTube(a), which offers a comparison of the topography of the region with Plato’s description of Atlantis. It includes a network of pre-Columbian waterways and a circular feature, which might have been the city. Antelo gives the following co-ordinates for the acropolis as 13° 09′ 35.6” S and 65º 33′ 36 .5” W.
Allan & Delair note that the Beni Basin is also home to features comparable with the Carolina Bays of North America[014.287]. In August 2013 the discovery was announced(d) of middens in the Beni region that were dated to 8000 BC.
Jim Allen, is the leading advocate of Atlantis in the Andes, specifically on the Altiplano to the west of Lake Poopo. Allen refutes Antelo’s claim at the end of a website(b) dealing with Plato’s Atlantis Plain.
Antelo published his thesis in 2008 in a book entitled La Conspiración Atlante (The Atlantis Conspiracy).
