A Roman marching camp of over 41 hectares, hidden until aerial photography found its ditches from the air in 1959 — physical proof that Severus's legions pushed deep into Moray.
Seen from the ground, the fields east of Keith give away nothing. It took an aircraft passing overhead in 1959 for the faint, rectangular outline of a vast Roman camp to show itself in the crop marks below — a shape almost 800 metres long that no one on the ground had ever noticed. Kenneth St Joseph, the pioneer of British aerial archaeology, spotted it and returned that same year to dig two small trenches across its defences.
What the marks traced was a marching camp, a temporary earthwork enclosure thrown up by a Roman army on the move rather than a permanent fort. Its scale, more than 41 hectares, matches the camps built for a full campaigning force rather than a small patrol, and it sits close to an earlier camp at Auchinhove associated with Agricola’s campaigns over a century before. Together they mark two separate Roman pushes into the same stretch of Moray, generations apart.
Muiryfold owes its identification entirely to that one season of flying and digging. No monument, wall or visible bank survives above ground for a visitor to walk up to; the site’s evidence lies in soil marks, ditch profiles and the historical record of an emperor determined to finish what Agricola had started.
What follows is drawn from published sources, with each claim labelled by how firmly it is established.
History
In 84 AD the Roman general Agricola pushed a campaigning army into the north-east of Scotland and established a marching camp at Auchinhove, near what would later become the site of Muiryfold. His advance marked the furthest reach of the first Roman incursion into this part of Caledonia, though the army did not stay to hold the ground it had crossed.
More than a century later, in 210 AD, the emperor Septimius Severus led a renewed attempt to subdue the whole of Caledonia, driving his legions north as far as the Moray Firth. As part of that campaign his forces built a marching camp at Muiryfold, close to the earlier Agricolan site, using the same favourable ground to shelter an army passing through the region.
The camp Severus's soldiers built was almost rectangular, stretching 784 metres from north-west to south-east and 522 metres from north-east to south-west, enclosing just over 41 hectares in total. A camp of that size was built to hold a substantial force for a single night or a few nights on the march, not to serve as a permanent garrison.
The site lay unrecognised for well over a thousand years until 1959, when Kenneth St Joseph identified its outline from the air through the faint cropmarks left by its buried ditches. Aerial photography of this kind was transforming the study of Roman Scotland at the time, revealing camps that left almost no trace visible from the ground.
Following the aerial discovery, St Joseph excavated two small trenches across the north-west and south-east sides of the circuit that same year, confirming the line and character of the defences seen from the air. His findings tied Muiryfold firmly into the wider pattern of Roman campaign camps stretching across eastern Scotland.
Discoveries at Portmahomack on the Dornoch Firth and Tarradale on the Beauly Firth later prompted speculation that Roman forces under Agricola or Severus might have pushed even further north than Muiryfold, but neither site has been confirmed as Roman. Muiryfold therefore remains among the northernmost securely identified camps of the Severan campaign.

Discovery & excavation
The camp was found by aerial photography in 1959, when Kenneth St Joseph identified its rectangular outline in cropmarks east of Keith. He excavated two trial trenches across the north-west and south-east defences that same year to confirm the discovery.
What to look for
-
The camp's footprint
No earthwork survives above ground to see; the camp's near-rectangular outline, roughly 784 by 522 metres, is known only from aerial photography and excavation records rather than from a visible monument.
-
The excavated defences
St Joseph's two 1959 trenches, cut across the north-west and south-east sides of the perimeter, established the profile of the camp's ditch and rampart line beneath the modern field surface.
