Mayburgh Henge is a large prehistoric monument in the county of Cumbria in northern England. Mayburgh Henge is just outside the village of Eamont Bridge close to the confluence of the Rivers Eamont and Lowther around 1 mile south of Penrith, just a few hundred yards from the M6 motorway.
Mayburgh Henge is in the care of English Heritage.
The site consists of a single circular bank built using cobble stones from the nearby rivers. The bank is up to 15 feet (6.5 metres) high, and 50 metres across its base with a diameter of around 383 feet (117 metres). Contained within it is a single monolith 9 feet (2.8 metres) high. According to Thomas Pennant, in the early 18th Century there had been four standing stones in the centre (marked on his 1769 plan, shown here), and a further four at the entrance, but his contemporary Robert Hutchinson, writing in 1773, gave a slightly different version:
"The inhabitants in the neighbourhood say, that within the memory of man, two other stones of similar nature, and placed in a kind of angular figure with the stone now remaining, were to be seen there, but as they were hurtful to the ground, were destroyed and removed."
No proper excavation has been done at Mayburgh, so it is difficult to date the henge with any certainty, but the presence of Neolithic and Bronze axes found near the site indicate a date in the Neolithic or Bronze Age.
There is no obvious explanation for why Mayburgh was built, but the fact that it is close to the confluence of the rivers Lowther and Eamont have given rise to the theory that it was once a trade centre on a route for stone axe trade from the Neolithic axe factory at Langdale.
Eden Arts Council erected a granite obelisk nearby, called the "Millennium Stone" to mark the year 2000.
