The Cart-Ruts of Malta are one of the many remarkable archaeological features of the archipelago. Unfortunately, the local authorities have not done all they could to ensure their preservation. Cart-ruts are also found in other countries but in nothing like the numbers found on Malta.
An article written in 1904(h) describes a visit to the Madeiras where the writer travelled on a sled drawn by oxen, while Alexander Braghine describes how Paul le Cour visited the Azores and noted that the natives there used ‘sledges’ rather than wheeled vehicles and greased the runners to assist movement, similar to the practice on the Madeiras. A more recent paper(s) by Félix Rodrigues of Azores University discusses in detail cartruts found on Terceira Island in the Azores. Other papers(w)(x) on the Academia.edu website discuss ‘ruts’ on Lanzarote in the Canaries.
“The earliest reference to cart-ruts was made by Gian Francesco Abela (1582–1655) in 1647  who suggested that they were used to transport stones from quarries to the sea for exportation to Africa during the Arab rule in Malta.”(z)
Dr. David Trump (1931-2016) who has done much to advance Maltese archaeology, published a booklet on the cart-ruts in 2008. Trump nicknamed the complex collection of ruts at Misrah Ghar il-Kbir “Clapham Junction” after the London railway station, where several railway services interchange. A 1998 paper(d) by Joseph Magro Conti and Paul C. Saliba focused on “Clapham Junction” and concluded that the ruts had a clear connection with the transportation of material from adjacent quarries.
A connection between the cart-ruts and Atlantis has been suggested by Anton Mifsud and adopted by the late Axel Hausmann, who both claim that the ruts were the irrigation channels referred to by Plato (Critias 118c-e).
Another prominent archaeologist, Claudia Sagona, has also suggested(f)(j) that the ruts were used for irrigation, although she has not associated them with Plato’s text. While this linkage fits nicely with the theory of Atlantis having been in the region of Malta, it does not stand up to close examination.
First of all the cart-ruts follow the natural undulations of the Maltese landscape and so to function as irrigation channels would require water to flow uphill for parts of its journey, Trump has mentioned how some of the ruts can be seen sloping as much as 45°. Roman aquaducts seldom used a gradient greater than half of one percent.
Secondly, the fact that the ruts are always found in pairs would suggest a degree of unnecessary and wasteful duplication found in no other irrigation system in the world. Because; if the ruts were intended to carry water, for the same labour they could have been cut as a single channel at twice the depth cutting losses through evaporation by half.
As well as that, the ground between each pair of tracks could provide an extra acre of arable land for every two miles of length. Furthermore, the multiplicity of tracks at the ‘Clapham Junction’ site is incompatible with an irrigation system.
All of which is compounded by the absence of controlling sluicegates anywhere at the remaining 100+ sites, and emphasised by Trump’s observation that “no association of ruts with water sources has been demonstrated.”[870.268]
I refer below to a number of countries where comparable cart ruts have also been found. I am not aware of even one instance where any of these have been suggested as having an irrigation function.
Compounding all that is the fact that no supporter of the cart ruts as Plato’s irrigation channels has attempted to explain how the dimensions of the ruts can be measured in inches while Plato describes canals measured in feet – tens of feet!
Joseph S. Ellul in his book Malta’s Prediluvian Culture  expressed some controversial unconventional views(t) regarding the cart-ruts, including his assertion that the ruts were created by tools or machinery and were formed during the Stone Age before the biblical Deluge!
By way of comic relief, I thought I should include one theory regarding an explanation(c) for the ruts from Laura Knight-Jadczyk, a noted conspiracy theorist, which I quote in full: “Do I have an idea to propose? Of course I do. I wouldn’t be writing about it if I didn’t. I would like to suggest that these “ruts” look an awful lot like places where lightning has struck, and the electricity has blasted away the dirt and rock as it shoots along some sort of natural earth power grid conductor. The only difference is that the cart ruts are not random. That suggests that there was something present in the ground laid out in a definite grid, which acted as a conductor. Were the cart ruts some sort of networked energy conduction system? Could some sort of element have been placed in the ground by an ancient civilization; something that that conducted power to their homes the way our vulgar power poles and lines criss-cross the landscape? And then, at some point in time, was the earth hit by such a surge of energy from some unknown source that these power “lines” melted the rock in which they were “strung?” Perhaps a surge of some kind of cosmic energy source? Maybe even the Electromagnetic pulse of a nuclear explosion? Maybe it was neither of these, but merely a massive overheating of the surface of the earth so that the conduction element and its insulating covering melted and was swept away?”
One of the more bizarre suggestions has been proposed by Markus Tutsch on the German EFODON website, that the parallel ruts were used in some way to distribute electrical power(q)!!!
Another comical suggestion is offered by Dr. Cornelius Niels Kopf who has proposed that “The Bronze Age traces on Malta and Gozo and many other parts of the then populated world, known as cart ruts, were sports facilities, and the area designated as ‘Clapham Junction’ was apparently the ‘stadium’ of Malta.” (r)
In 2010, the most comprehensive work on the ruts was published by Gordon E. Weston. Weston now has a website(g) where he discusses the ‘ruts’ further and provides additional links. Weston also published Clapham Junction: 3000 Years of Maltese Heritage, in 2015 .
There are also a number of websites devoted to the investigation of these enigmatic features(a). One of them(m) offers a fine collection of images, including the one above, as well as a discussion on the origin, use and questions raised by the Maltese cart ruts.
A study of the ruts by geomorphologists published in Antiquity is a valuable addition to the literature on the subject(b).*The authors highlight the fact that the relatively soft Maltese limetone erodes quite easily, particularly when wet, explaining the depth of the ruts.*
Uwe Topper has written an extensive paper on cart-ruts around the Mediterranean and beyond(i). He controversially theorised that that the ruts were created when the limestone on which they were cut was ‘softer’!!!
A short April 2015 video clip(l) demonstrates how even a 20kg quarter-scale slidecar, can with one pass cut a 1mm groove into the soft Maltese limestone, near Sliema. A full scale slidecar would be carrying 320 Kg.
Amateur archaeologists, Ronnie Gallagher and Abbas Islamov, have highlighted the existence of cart-ruts in the Gobustan peninsula of Azerbijan(e), while André Kramer has written an article on the cart-ruts of Mallorca(k).
Evidence exists for cart ruts in other countries in Europe, such as Switzerland and much further afield including South America(u). The same site makes two interesting points, (1) since the earliest carts probably lacked brakes, the repeated use of the ruts gave some small degree of control and (2) without any obvious passing points the ruts seem to indicate that they were limited to one-way traffic.
In 2015, Russian geologist Alexander Koltypin drew much media attention(o) when he claimed that comparable tracks in the Phrygian Valley of Turkey were dated to 14 million years ago and were created by an unknown civilisation. He also implied that the cart ruts of Malta had similar origin! However a quick look at his website(p) revealed him to have travelled well beyond the lunatic fringe.
I find it interesting that much more investigation of the Maltese cart ruts has been carried out by foreigners than by natives of the islands. A recent example is the inventory of ruts recently published by Monika I. Trinkler, a Swiss photographer. She has listed 652 pairs on Malta and 42 on Gozo. Her interested in the Maltese ruts has now expanded into the identification of ruts throughout Central Europe.(v)
Unfortunately, the date and function of the ruts are still sources of intense debate, particularly in Malta itself. In 2017, Anthony Bonanno published The Archaeology of Malta and Gozo  in which he argued for a Roman rather than a prehistoric date for the cart ruts. This runs counter to the opinion of many, particularly that of the late David Trump. In 2019, Anton Mifsud published a rebuttal of Bonanno’s claims in a fully illustrated book entitled David’s Ruts  as a tribute to the work carried out by David Trump on Malta.

The Azores (Açores) is a group of Portuguese islands in the Atlantic, situated 740 miles from the mainland. The first recorded instance of their discovery is in 1427 by the Portuguese, although there is some evidence to suggest a much earlier date. In 2012, the president of the Portuguese Association of Archeological Research (APIA), Nuno Ribeiro, revealed(c) that rock art had been found on the island of Terceira, supporting his belief that human occupation of the Azores predates the arrival of the Portuguese by many thousands of years. A further article(a) in October 2016 expanded on this matter. Ribeiro’s research was trotted out in a more recent documentary from Amazon Prime with the tabloid title of New Atlantis Documentary – Proof that Left Historians Speechless(u), which explores the claim that the Azores are the mountain tops of sunken Atlantis!
However, the Portuguese authorities set up a commission to look into Ribeiro’s contentions and concluded(q) that any perceived remnants of an ancient civilization were either natural rock formations or structures of more modern origin. Nevertheless, as the Epoch Times reports(r) that “Antonieta Costa, a post-doctoral student at the University of Porto in Portugal, remained unconvinced and continued research into the hypothesis that the Azores were inhabited in antiquity and even in prehistory.”
It is thought that the Phoenicians and Etruscans competed for control of the Azores in later years. In 2011 APIA archaeologists reported that they had discovered on Terceira island, a significant number of fourth century BC Carthaginian temples. They believe the temples were dedicated to the ancient Phoenician/Carthaginian goddess Tanit(c). The Jesuit, Athanasius Kircher, in his 1665 book Mundus Subterraneus, was first to propose that these islands were the mountain peaks of sunken Atlantis. This view was adopted by Ignatius Donnelly and developed by successive writers and still supported by many today. The latest recruit is Carl Martin, who is current working on a book locating Atlantis in the Azores and destroyed around 9620 BC. The late Christian O’Brien was a long-time proponent of the Atlantis in Azores theory. A bathymetric study of the area suggested to O’Brien that the archipelago had been a mid-Atlantic island 480 x 720 km before the end of the last Ice Age. Apart from the inundation caused by the melting of the glaciers he found evidence that seismic activity caused the southern part of this island to sink to a greater degree than the north. O’Brien pointed out that six areas of hot spring fields (associated with volcanic disturbances) are known in the mid-Atlantic ridge area, and four of them lie in the Kane-Atlantis area close to the Azores. In 1982 Peter Warlow suggestedthat a sea level drop of 200 metres would have created an island as large as England and Wales with the present islands of the Azores as its mountains. However, Rodney Castleden contradicts that idea[225.187] saying that if the sea level was lowered by 200m “the Azores would remain separate islands.” Bathymetric mapsof the archipelago, above and on the Internet(g), verify Castleden’s contention. This together with an 1982 paper from P.J.C. Ryall et.al, which demonstrates more clearly that the Azores are just the summits of volcanic seamounts that rise from an underwater plateau that is 1000 metres below sea level. Professor Ryall and his associates were dealing objectively with the geology of the area and were not promoting any view regarding Atlantis. The geological evidence supporting an Azorean Atlantis is therefore very weak, verging on the non-existent.
Andrew Collins, the leading proponent of a Cuban Atlantis, has written a short review of the Azorean Hypothesis(h).
Frank Joseph has offered his views on Atlantis in the Azores in a YouTube video(l).
Nikolai Zhirov recounts in his book[458.363] how Réne Malaise wrote to him regarding a Danish engineer named Frandsen who identified a plateau, 2/3rds the size of Finland, south of the Azores, whose summits were 4,000-5,000m metres higher than it. Adding canals gave Frandsen a configuration that closely matched Plato’s description of Atlantis. Zhirov also noted[p403] that in 1957 a journal entitled Atlantida was published in the Azores.
In 1976, Jürgen Spanuth pointed out[015.249] that the Azores are not the mountain peaks of a sunken continent but instead are volcanic rock created through eruption. He quotes similar sentiments expressed by Hans Pettersson. A 2003 paper(b) by four French scientists demonstrated that the Azores had been greatly enlarged during the last Ice Age. However, showing that the Azores were more extensive is not disputed, but it in no way demonstrates that it was the location of Atlantis. In fact Plato’s description of the magnificent mountains to the north and the mud shoals that were still a hazard in Plato’s day do not match the Azores. The geologist, Darby South, strongly denied that the Azores could have been the location of Atlantis according to a couple of articles posted on the internet some years ago(a). However, natives of the archipelago are quite happy to assert a link with Atlantis, as travel writer David Yeadon found on a visit there(d). Nevertheless, advocates of Atlantis in the Azores must accept that there is very little evidence of human occupation in prehistoric times, apart from the rock art mentioned above. When the Portuguese arrived on the island in the 15thcentury they were found to be uninhabited and without any evidence of an earlier civilisation there. Initially, the only hint of earlier visitors was some 3rd century BC coins from Carthage discovered on the island of Corvo. However, in recent years Bronze Age rock art(f) and what is described as a Carthaginian temple(e) have both been discovered on the island of Terceira.
Otto Muck among others, was certain that the enlarged Azores had deflected the Gulf Stream during the Ice Age, contributing to the extent of the western European glaciation. However, a 2016 report(m) from Center for Arctic Gas Hydrate, Climate and Environment (CAGE) offered evidence that the Gulf Stream was not interrupted during the last Ice Age, which would seem to undermine one of Muck’s principal claims.
Nevertheless, it is still far from clear what caused the ending of the last Ice Age. A number of writers including Muck speculated that an asteroidal impact in the Atlantic was responsible. When the Azores were discovered in the 15th century they were uninhabited and without any evidence of an earlier civilisation. It can be reasonably argued that since the Azores today are just the mountain peaks of a larger mainly submerged island, any remains would be more likely to be found on the plains and estuaries that are now under water. One undeveloped theory is that the name ‘Azores’ might be linked to the ninth king of Atlantis, Azaes, listed by Plato. This idea is supported by the linguist Dr. Vamos-Toth Bator. However, a Portuguese correspondent has pointed out that the Azores is named after a goshawk (Accipiter gentilis) commonly found on the islands and portrayed on the regional flag. The renowned writer, Dennis Wheatley, used the possibility of Atlantis being located in the Azores as a backdrop to his 1936 thriller, They Found Atlantis.
In August 2013 Portuguese American Journal reported that the many pyramidal structures on Pico are clear evidence of extensive human activity in the archipelago long before the arrival of the Portuguese(o). A YouTube video(p) offers some interesting views of the pyramids.
The following month the same journal announced the discovery of a pyramidal structure 60 metres high at a depth of 40 metres off the coast of the Azorean island of Terceira(i). Shortly afterwards the Portuguese Navy denied the existence of any such structure(j). Not exactly a surprise! Nevertheless, an Italian website has attempted to breathe new life into the story by linking this underwater pyramid report with pyramidal structures found on the island of Pico(k).
The Wikiversity website has an extensive article(s) on the location of Atlantis, which is focused on the Azores and the bathymetric evidence for that archipelago having being a large single landmass at the end of the last Ice Age, when sea levels were much lower. However, it is based on the literal acceptance of Plato’s 9,000 years before Solon for the date of the Atlantean War.
April 2018, saw British tabloid interest in Atlantis revived with further speculation on the Azores as the location of Plato’s submerged island(t). However, the details of the claim were rejected by Dr. Richard Waller a lecturer at Keele University. Not content with recycling the old Azores theory, The Star also throws in the even more nonsensical idea of an Antarctican Atlantis.
