Royston Cave remains an enigma, offering a rare glimpse into the past and sparking curiosity about its true purpose.
History and Origins
1742 Discovery
In August 1742, workmen installing a bench at Royston's butter market stumbled upon an unexpected find - a millstone embedded in chalk.
As they dug deeper, they uncovered a narrow shaft leading to a bell-shaped chamber. Inside, they found earth, debris, human remains, and intriguing artifacts, including a skull, fragments of an ancient drinking vessel, and a piece of brass.
This remarkable discovery sparked curiosity and laid the groundwork for the legends surrounding the cave, particularly its rumored connection to the Knights Templar.
Knights Templar Links
The cave's ties to the Knights Templar have long been a source of intrigue. Historical records confirm the Templars were active in the area, founding the nearby town of Baldock in the 1140s and engaging in trade at Royston's butter market between 1149 and 1254.
"The risk here is people have been wanting to tell stories since day one: 'Come and see the Templar cave!'" – Tobit Curteis, cave conservator
Local historian Sylvia Beamon has suggested that the cave may have been used by the Templars for practical purposes, such as food storage, daily prayers, or even as temporary lodging during their market visits.
However, not everyone agrees on a direct Templar connection. In 2012, a stylistic analysis conducted by the Royal Armouries Museum in Leeds dated the cave's carvings to between 1360 and 1390 - well after the Templar period had ended. This dating has led some historians to question the cave’s direct link to the Templars.
Ancient Trade Routes
The cave’s location beneath the crossroads of Ermine Street and Icknield Way highlights its strategic importance. Ermine Street was a major Roman road connecting London to York, while Icknield Way, often considered Britain’s oldest road, stretched from East Anglia to Salisbury Plain.
This prime position along key trade routes underscores the cave’s historical significance and raises the possibility that it served as a hidden sanctuary or waypoint for travelers navigating these ancient pathways.

Cave Design and Carvings
Royston Cave isn’t just a historical curiosity - it’s a space where architecture and symbolism intertwine, creating layers of intrigue.
Bell-Shaped Structure
The cave’s bell-shaped chamber, carved directly into chalk, reflects both medieval craftsmanship and symbolic intent.
This design is thought to echo the Etruscan concept of mundus - a sacred shaft believed to connect the living world with the afterlife. The cylindrical base rising into a domed ceiling mirrors the celestial vault, emphasizing its spiritual undertones.
"Tis of an elegant bell-like, or rather mitral form, well turned, and exactly circular" - Dr. Stukeley
Wall Carvings
The walls of Royston Cave are adorned with an extraordinary array of medieval carvings, setting it apart from other subterranean chambers in Britain. A 2012 analysis by the Royal Armouries Museum dated these carvings to between 1360 and 1390, based on the costumes and hairstyles depicted.
Among the carvings are significant religious figures, including St. Catherine, the Holy Family, the Crucifixion, St. Lawrence, St. George (or possibly St. Michael), and St. Christopher.
One particularly intriguing carving shows two knights sharing a horse, which could be a nod to the Knights Templar. Another depicts a figure holding a skull and candle, hinting at initiation ceremonies.
"We've lost 99% of the other artwork from that period, so the cave really is incredibly special. Just maybe not for the reasons that some people think." - Tobit Curteis, Cave Conservator
Platform Evidence
Beyond the carvings, the cave’s structural features suggest it was more than just a canvas for medieval art.
A 1976 examination uncovered remnants of an octagonal step, post holes, and wall niches - evidence pointing to a sophisticated wooden platform system. This platform likely had both ceremonial and practical uses.
Former cave manager Peter Houldcroft’s reconstruction analysis revealed a free-standing structure that optimized the cave’s space. It allowed access to upper wall niches while also supporting ritual activities.
The octagonal step and platform design align with historical accounts of medieval sanctuaries, suggesting the cave was meticulously planned to serve dual purposes: storage and spiritual ceremonies.
Energy Properties
Earth Energy Lines
Royston Cave's location is uniquely tied to the Earth's natural energy pathways. It sits at the convergence of ancient ley lines - those unseen, mystical routes believed to channel the planet's energy.
One of these, the Michael Line, famously intersects with another energy line near the cave. This same line also passes through iconic sites like Stonehenge and Avebury.
Adding to its intrigue, the cave lies about 26 feet (8 meters) beneath the historic crossroads where the Icknield Way meets Ermine Street. It's possible this spot was chosen deliberately. Some historical accounts even suggest that the Knights Templar may have used dowsing techniques to locate and potentially influence these energy currents.
Reported Effects
The energy currents at Royston Cave seem to have a noticeable impact on visitors' sensory experiences. Studies have shown that within enclosed cave environments, oxygen levels can drop from 21% to 18% in just 15 minutes.
This mild reduction in oxygen, or hypoxia, can trigger increased dopamine release. Such physiological changes might explain the unique sensory perceptions reported by those who visit the cave - sensations that stand out from typical underground experiences.
Natural Factors
Several physical features of the cave amplify its effects:
- The chalk bedrock highlights the distinct geology of the area.
- Its depth and isolation create a heightened sensory environment.
- The chamber's shape enhances its acoustic qualities.
Research has demonstrated how conditions like sensory deprivation, darkness, and specific acoustic environments can disrupt circadian rhythms and shift perceptual states. Yafit Kedar, a Doctoral Candidate in Archaeology and Near Eastern Cultures at Tel Aviv University, elaborates:
"We contend that entering these deep, dark caves was a conscious choice, motivated by an understanding of the transformative nature of an underground, oxygen-depleted space."
The cave's location at the intersection of ancient trade routes, combined with these natural characteristics, suggests a deliberate selection of the site to amplify its ceremonial or spiritual significance. Modern research continues to uncover how these elements may have been used to create profound experiences for those who entered.
Templar Ceremonies
Dark Room Rituals
The unique design of the cave hints at its potential use for Templar rituals. For instance, a shallow depression in the eastern wall, paired with an octagonal step, suggests a specific ceremonial area.
Adding to this theory is a carving of a figure holding a skull and candle - symbols often associated with initiation rites. Evidence of post holes indicates that wooden platforms once existed, likely elevating parts of the chamber to access niches used during ceremonies.
The lighting appears to have been carefully controlled with oil-burning lamps, while an eastern ventilation shaft helped manage airflow. These features have fueled speculation and legends, including tales connecting the site to the Holy Grail.
Grail Connections
Some legends tie the cave to the mysteries of the Holy Grail, drawing comparisons between its circular design and the Church of the Holy Sepulchre in Jerusalem. However, historical records suggest that the Templars likely used the cave for more practical purposes - prayers, food storage, or even lodging during market days - rather than as a sacred Grail chamber.
"In real life, the Templars were not a subterranean order." – Professor Helen Nicholson
The site’s practical uses, especially during periods of tension with the nearby Royston Priory, seem more plausible based on historical evidence.
Similar Sites
Studies comparing Royston Cave to other medieval locations reveal some intriguing parallels. A stylistic analysis conducted in 2012 dates the carvings to around 1350 - well after the Templars' active era. While the cave's circular design is notable, round churches were common in areas unrelated to Templar activity.
"What makes the cave so intriguing to visitors and historians is that it's still an enigma; still a mystery as to who made it, or when or why." – Nicky Paton
The mystery deepens due to the damaged state of key carvings, including the famous two-knight image. These deteriorations make it challenging to draw firm conclusions about the cave's original purpose.
