Hardknott Roman Fort in Cumbria, England

Ancient Roman fort in England may have been constructed to pay homage to Mithra or Sol Invictus

A new study shows that the builders of an ancient Roman fort in northern England aligned it so the sun’s rays shone through the gates at dawn and sunset on the winter and summer solstice. The researchers suggest that that construction of the fort was designed in such a way for the inhabitants to engage in sun worship and pay homage to solar deities.  

The fort, now in ruins, was near Hardknott Pass overseeing the River Esk on the northern frontier of the Roman Empire during the reign of Hadrian, 117 to 138 A.D, located in what is now Cumbria, England.

The researcher who made the discovery by studying the fort’s alignment using online software, said it could have been built in homage to solar deities Mithra or Sol Invictus. Mithra, whose cult was solely male and who was worshipped especially by soldiers, was so powerful the sun was believed to kneel to him.

The fort, overlooking the Eskdale Valley, was arranged in a square with the four gates in the center of the four walls. During the annual June 21 summer solstice sunrise, the sun’s rays shone through the fort’s northeastern and southwestern gates. At sunset on the longest day of the year, sun rays shone through the northwestern and southeastern gates, physics researcher Amelia Carolina Sparavigna wrote in the journal Philica .

On the December 21 winter solstice, or the lowest point of the sun in the sky and the shortest day of the year, the sun rose in alignment with the southeastern and northwestern gates and set in line with the southwestern and northeastern gates, she wrote.

The fort’s “distinctive layout … [has] an orientation of its axes to solstices, so that, through its four gates, we could imagine to see sunrise and sunset on those days,” she wrote in Philica.

Sparavigna said the four towers in the corners of the fort were aligned with the cardinal directions. The fort sat on the landscape in a diamond shape, with one corner and its tower almost directly north, one to the south and the other two to the east and west.

If the idea of the fort’s layout was to place its towers at corners in the north, south, east and west, it may be a coincidence of nature that the rising and setting sun’s rays shone nearly exactly through the gates to the northwest, northeast, southwest and southeast during solstices. Nevertheless, Sparavigna told Live Science that it was common for cultures  at the time to align their buildings to solar and celestial events.

"An orientation of sacred places to sun and sky is common to several religions," Sparavigna told Live Science. She said it’s "quite possible that the Hardknott fort has a symbolic homage to the sun. The god could be Sol, the ancient Roman god of the sun, which evolved [into] Sol Invictus." Sol Invictus means “unconquered sun.”

She said another god, Mithra, is possibly the inspiration for the fort’s solar construction. Mithra was a Persian god that became popular with Roman soldiers and the male general populace. Mithra himself was referred to as Sol Invictus in the Roman Empire.

“The [Mithra] cult was all male. There were seven degrees of initiation. Different ritual meals were associated with each stage,” says Tertullian.org . “It is certain that Mithras is born from a rock. He is depicted in his temples hunting down and slaying a bull. … He then meets with the sun, who kneels to him.”

The New Larousse Encyclopedia of Mythology said in pre-Zoroastrian Persia, Mithra was associated with the supreme being Ahura and “was a god of the first magnitude.” His wisdom and military valor were unsurpassable. “He possessed not only strength but at the same time knowledge, for in essence he was Light. As such he led the solar chariot across the sky,” the encyclopedia says.

Sol Invictus was a later Roman sun deity who was separate from Mithra. He was patron of soldiers. Scholars disagree as to whether he is simply a newer version of the old Latin cult of Sol, or the sun as god.

Sparavigna said several other Roman towns in Italy are aligned with the solstice sun. The northern African town of Timgad is aligned in the direction of the sunrise on the birthday of the Trajan, the Roman emperor who reigned from 98 to 117 A.D.


Thank you April. I have not seen this depiction before...I was wondering the other night why in some that I had seen the image of the person holding the torch down on one side of Mithra and the bull and up on the other.....now I see. Inanna on one side and Sin her father and the Moon god on the other.....Mithra the sun. The three brightest celestial bodies as seen from earth, Venus, the sun and the moon. The bull is Nergal, the husband of Ereshkigal, the ruler of Hades. Venus is not a planet, she is a comet trapped in the solar system, like Persephone who holds the torch in Hades. This is why she has a cresent shape. So what is the yellow brick road?
Mithra was born from a rock that had a snake wrapped around it and a cluster of grapes (portal) at the corner....he comes from outside this solar system to slay Nergal.
Are we about to see some major changes in this world?
This is all a bit crazy, but to me it is more real than the insanity that exists outside of my locked gate. What is reality? Maybe when one reality becomes too cruel to bear....we choose to consider an alternate.

Myths & Legends

Open Book Photo
A legend is a tale regarded as historical even though it has not been proven, and the term “myth” can refer to common yet false ideas. Many myths and legends describe our history, but they are often treated skeptically. This is because many of them, while explaining a phenomenon, involve divine or supernatural beings.

Human Origins

The imperfect state of archaeological researches in the Near East impedes any definite identification of the original race or races that created the earliest civilizations of Mesopotamia and Egypt. According to Gordon Childe, however, the predominant racial element in the earliest graves in the region from Elam to the Danube is the ‘Mediterranean’.

Deep in the heart of Saudi Arabia, 400 peculiar stone structures have been found, dating back thousands of years ago. These stone features were discovered by archaeologists with the use of satellite imagery, identifying what they call stone "gates" in an extremely unwelcome and harsh area of the Arabian Peninsula.

In 1995, NBC televised a prime-time documentary hosted by actor Charlton Heston and directed by Bill Cote, called Mystery of the Sphinx. The program centered on the research and writings of John Anthony West, a (non-academic) Egyptologist, who, along with Dr. Robert Schoch, a professor of Geology at Boston University, made an astounding discovery on the Great Sphinx of Giza in Egypt.

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
