Mysteries of the King’s Men Stone Circle at the Rollright Stones

Image
The King’s Men is the largest and best known of the prehistoric monuments at the Rollright Stones, a prehistoric complex on the Oxfordshire and Warwickshire border. It is one of the most distinctive stone circles in southern England and has attracted visitors, researchers and people interested in the unexplained for generations. The monument has been approached from very different perspectives. Archaeologists have investigated its prehistoric remains and surrounding landscape, while other investigations have explored unusual physical phenomena and reports of experiences among the stones. Alongside these investigations is a long tradition of what is now described as Earth Mysteries, including accounts of energy patterns and other effects perceived at the site. This article looks at one particular aspect of that history: a reported spiral pattern within the King’s Men and the experience we had when we decided to follow it for ourselves. Before getting to that experience, however, it is w...

6 Ancient Stone Features of Machu Picchu Worth Discovering

Image
Most descriptions of Machu Picchu focus on its terraces, temples and finely fitted masonry. Those are undoubtedly impressive, but they can also distract from another aspect of the site that deserves equal attention. Throughout Machu Picchu are a series of stone monuments that differ from the surrounding architecture. Some were carved directly from the mountain itself. Others were created by leaving natural granite outcrops almost untouched while building carefully planned structures around them. Together they suggest that, at certain locations, the stone itself was just as important as the buildings constructed nearby. A wall is an architectural element. A monument is a focal point. Throughout Machu Picchu there are places where the natural granite appears to have been selected, modified or framed in ways that set it apart from ordinary construction. Whether these features served astronomical, ceremonial, symbolic or practical purposes remains open to discussion. What can be observed, ...

The Chinkanas of Cusco

Image
Most visitors who arrive at Sacsayhuamán are captivated by its immense zigzag walls, where limestone blocks weighing many tonnes fit together with astonishing precision. Yet one of the site's greatest mysteries does not stand above the ground at all. It lies beneath their feet. Among the limestone outcrops on the northern side of the archaeological complex are a series of underground passages known as the Chinkanas. Although they receive only a fraction of the attention given to the monumental walls nearby, these tunnels have fascinated explorers, historians and local residents for centuries. Some visitors see nothing more than a few dark openings cut into the rock, while others believe they are the surviving entrances to an extensive subterranean network extending beneath ancient Cusco. The word chinkana comes from the Quechua language and is generally translated as a place where one becomes lost, a labyrinth or a hidden passage. The name is remarkably appropriate because almost e...

Palma Sola: The Ancient Petroglyphs Overlooking Acapulco

Image
When Palma Sola is mentioned, the discussion usually begins with its petroglyphs. Researchers have catalogued the engravings, described recurring motifs, and proposed interpretations ranging from ritual symbolism to astronomical observation. These studies have expanded our understanding of the site, yet they often leave a broader question unanswered. Why were these engravings created on this particular hillside instead of somewhere else? Located on the southern slopes of El Veladero in Guerrero, Mexico, Palma Sola preserves nearly twenty engraved granite outcrops dating between approximately 200 BC and AD 600. The engravings depict human figures, animals, footprints, spirals, concentric circles, geometric designs, and abstract motifs. They were produced by pecking and abrading naturally exposed granite rather than carving prepared stone blocks or constructing monumental architecture. What distinguishes Palma Sola is not simply the quality or variety of its engravings but the way they a...

Rethinking the Giza Plateau

Image
Ask someone to describe Giza and they will almost certainly mention the pyramids and the Great Sphinx. Ask the same person what the Giza Plateau is, and most people will struggle to answer. That is surprising because the plateau is the reason Giza exists. Without it there would be no pyramids, no Sphinx, no temples, no underground network, and perhaps no Giza as we know it. The monuments have dominated our attention for centuries. But when you look beyond them, a different picture begins to emerge. Every major structure at Giza is connected to the same body of limestone. The pyramids stand on it. The Sphinx was carved from it. The temples were constructed with stone taken from it. The causeways follow its natural slopes. The underground chambers disappear into it. None of these features exist independently. They are all part of one continuous geological landscape. This changes the way we think about Giza. Instead of asking how the pyramids were built, perhaps we should begin by asking ...

The Future of Ancient Sites

Image
Ancient sites have survived ice ages, wars, political upheaval, and the rise and fall of countless civilizations. Stone circles still stand where prehistoric people raised them thousands of years ago. Temples continue to overlook valleys long after the cultures that built them disappeared. Ancient cities emerge from forests and deserts to remind us that human history is far older and often far more complex than we imagine. Yet despite their apparent permanence, ancient sites are entering one of the most significant periods of change in their history. For most of human existence, the threats facing ancient places were relatively predictable. Weather slowly eroded stone. Vegetation reclaimed abandoned settlements. Occasionally a monument would be destroyed through conflict, development, or neglect. Today, however, a combination of new technologies, climate pressures, mass tourism, and changing cultural attitudes is reshaping the future of ancient sites in ways that would have been unimag...

The Lost Triple Spiral Geoglyph of Peru

Image
In June 2026, Peru lost one of its lesser known but most distinctive archaeological monuments when the Triple Spiral geoglyph in the Quebrada Santo Domingo Archaeological Zone near Trujillo was reportedly destroyed. Although it never achieved the international fame of the Nazca Lines, the Triple Spiral was an important part of Peru's archaeological heritage. The geoglyph had survived for well over a thousand years in the arid landscape of La Libertad region and represented one of the few known examples of a large spiral motif created directly on the ground in northern Peru. Its destruction has renewed concerns about the protection of archaeological sites across the country and has drawn attention to a monument that many Peruvians had never heard of before its disappearance. What Was the Triple Spiral? The Triple Spiral was a geoglyph located within the Quebrada Santo Domingo Archaeological Zone in the district of Laredo, east of Trujillo. The design consisted of three interconnecte...
