The layout of a Peeblesshire Roman fort, believed to have been built and then quickly abandoned by Agricola's troops in the first century AD will be surveyed in detail by a team of archaeologists and enthusiasts in a bid to uncover its hidden history.
Photographs taken from an aircraft in 1955 first identified the fort at Easter Happrew next to the Lyne Water, a tributary of the River Tweed. A brief excavation on a small part of the site was carried out the following year before it became a scheduled monument in 1959.
According to some scholars the briefly occupied fortifications bear the Latin name Carbantoritum. It was one of a series of military structures put up by the invading armies as they took control of the South of Scotland.
The new investigations over a five-day period at the end of January are part of the exciting Uncovering the Tweed programme which has already been featured in these columns.
In the words of Katie O'Connell, of AOC Archaeology, the specialists leading the Uncovering the Tweed initiative for Tweed Forum, the work at Easter Happrew will offer members of the public the chance to witness a geophysical survey of the fort. "This project will include magnetic gradiometer and earth resistance surveys, providing a hands-on chance to uncover history while learning advanced archaeological techniques."
The aerial photos showed traces of three timber-framed buildings and the 1950s excavation revealed gravel roads in and around the fort.
According to the project organisers: "There is some evidence for annexes, but they are not clearly understood. The survey will provide a better understanding of the layout and survival of the fort. The ditches which have been levelled by cultivation may still be detectable by gradiometer survey.
"The resistance survey will hopefully map remnants of stone structures, if present, and the layout of roads, while the gradiometer survey may identify postholes associated with wooden structures. As a result these non-invasive surveys will hopefully provide important information on the layout and development of the site, but also on its current state of preservation following decades of cultivation."
Historic Environment Scotland's entry for the scheduling of the Easter Happrew fort includes additional details.
"The fort is rhomboid in shape measuring around 140m across with three visible entrances, on the east, west and south sides. The north side of the fort has been eroded by the Lyne Water. The aerial photography shows that the fort is bisected by a road.
"There is an annexe measuring around 140m by 70m on the southwest side of the fort. Excavations suggest that the commander's house stood to the north of this road, near the eastern gate and the fort faced south. Outside of the fort on its northeast side are at least three buildings which may be civilian rather than military in nature."
The fort is deemed to be of of national importance because it makes a significant contribution to 'our understanding or appreciation of the past, or has the potential to do so', in particular in relation to the earliest period of Roman occupation of Scotland, and the construction, use, dismantling and abandonment of Roman frontier military installations during this period.
And the scheduling entry adds: "The monument is a rare example of an early Flavian fort in Scotland, apparently unaltered once it was abandoned in favour of the nearby fort at Lyne.
"The monument has research potential which could significantly contribute to our understanding or appreciation of the past, in particular, it holds the potential to enhance our understanding of the early Roman presence within Scotland, including the construction and use of Roman military architecture in the late 1st century AD, the social and economic conditions surrounding them, and their relationships over time, and there is high potential for archaeological evidence to survive in and around the monument."
The monument has significant associations with Gnaeus Julius Agricola, the Roman Governor of Britannia and military commander of multiple campaigns into Scotland during the late 70s and early 80s AD, culminating in his victory in the Battle of Mons Graupius around 83AD.
The 1956 'dig' revealed important information on the date and character of the fort. These excavations showed that the fort was enclosed by a turf rampart around 8m wide with a ditch 4m wide and around 1.5m deep in front of it. The front portion of the rampart stood on a stone base, presumably to minimise the likelihood that it might collapse into the ditch.
Behind the rampart was an area of ash, likely from ovens and beyond that lay a gravelled road. A small section of the garrison commander's house (the praetorium) was also uncovered. This was a timber building with wattle and daub walls. The excavations did not show any sign of repair or reconstruction which suggests that the fort was occupied only once and was then never re-occupied.
The survey work at Easter Happrew is due to run from from January 27th-31st.
