Achnasoul and Medieval Earthwork Castles in Ross Revisited

by Meryl Marshall

The moated homestead in Achnasoul Wood (NGR NH 48808 51821 Canmore ID: 274702 Highland Council (HC) HER MHG29192) 4kms west of Muir of Ord was visited by NOSAS members on a winter walk in February 2020 just before “lockdown”. The visit renewed my interest in the medieval period in this area and I began some research into the two homesteads of Davids Fort and Achnasoul with the intention of producing a blog for the NOSAS website. It wasn’t long before I realized what a complex topic I had taken on so I decided to split it into two; the first part, on Davids Fort, appeared on the NOSAS website in May 2020, this piece, focusing on Achnasoul, is part two.

The Achnasoul site is a ringed earthwork with a central mound which was originally interpreted as a “moated homestead” but recently confirmed (on Canmore) as a motte and bailey. It is remarkably well preserved and has been one of my favourite local sites for many years. NOSAS carried out a planetable survey on a cold, wintery day in 2005 (report on NOSAS website at: www.nosas.co.uk/siterecords.asp.) The site remains something of a mystery and seems out of place; clearly it is fortified as it has substantial double banks enclosing a ditch but yet it is situated in low lying ground with higher knolls surrounding it – not a particularly defendable position!

In 2017 the site was scheduled by Historic Environment Scotland (HES) – SM13629. The description in the scheduling document says:               

The monument is a large earthwork enclosure comprising a ditch and two concentric banks which enclose a sub-circular area measuring around 43m northwest-southeast by 39m northeast-southwest within which is a raised mound. The ditch defining the enclosure measures 4m to 5m in width and 1.5m in depth and is broken by two causeways on the northwest and southeast. The outer bank of the ditch is complete and varies in height, reaching a maximum of 2m… Internally, the raised mound lies in the northern part of the enclosed area and is c25m diameter at its base, reaching a maximum height of 2m. The summit is encircled by a fragmentary bank, which encloses an area of around 11m diameter.

The size and form of the visible remains… represents a rare survival of a moated homestead of medieval date.

David’s Fort Revisited – and a Strange Coincidence?

By Meryl Marshall

With movements restricted due to the coronavirus pandemic it was inevitable that I would find myself at David’s Fort, near Conan House, just 2kms from my home. This impressive earthwork, variously interpreted as a “motte”, a “moated homestead” (OS map) and a “moated site” has received lots of attention from NOSAS in the past, see Marion Ruscoe’s blog of 2016, but the site remains as mysterious as ever. I was pleased to see that the area is much more open than it used to be, but the surrounds are rapidly becoming overgrown with scrubby brambles, broom and whins. The visit set me thinking once again about the origins and history of the site, with more time at home I set about some online investigations.

David’s Fort (Canmore ID: 12866, Highland Council HER: MHG8986) is at NGR NH 5394 5328 and consists of an impressive wet ditch 4m deep enclosing a trapezoidal area measuring 25m from N to S and 26m to 32m transversely. The ditch is enclosed by an external bank standing up to 3m height but 1.5m externally. Internally the only feature visible is a circular depression 7m in diameter and 1m in depth in the western half; traces of what may have been a bridge spanning the ditch on the west side have also been reported (June 1979) The moat still contains water and was originally fed by a waterway running from an artificially constructed pond possibly of more recent origin 100.0m to the east, to a cut in the bank at the NE corner.

The site is located on the forested slope above the River Conon 1km to the east of Conan House. It is close to what, in the Medieval period, was a crossing of the River Conon. Here too was the old church of Logiebride (or Logie Wester), and the site of the Battle of Lagabraad in 1481. This area, at the “neck” of the Black Isle, will almost certainly have been a meeting point of routeways for centuries, if not millennia.

NOSAS in Forres: A Visit to the Medieval Burgh

by Dr John R Barrett

Forres folk are suspicious of strangers – and especially suspicious of foreign strangers who pretend to know something about Forres history. And I should know. Having worked as an archivist in the royal burgh for barely thirty years, and lacking at least three Forresian grandparents, I am still a couple of generations short of qualifying as any kind of expert on Forres history.

And Forres is suspicious of people from the North. Long local memories recall a time when Moray held the front line against the Vikings; and longer memories of local independence are now reinforced by academic research that places Pictish Fortriu in Moray (or Moray in Fortriu) – the Pictish kingdom persisting as the heartland of the Cenel Loarn branch of the Dalriadan Scots.

But, despite this history (and also because of it) I rashly accept an invitation to guide NOSAS around the royal burgh.

We choose a day of icy wind and leaden skies. We gather in a draughty car park for the prelims (safety check, head count, toilet break). And then there are the necessary explanations: this will be a walk in feet and inches – a concession to my age, and also because (notwithstanding modern archaeological practice) the place was built to an older yardstick.

We note the regular snaking roods[i] of burgh biggid land that curve sinuously from high street frontage to head dyke (at the foot of the feu) with back passage beyond.  The linked head-dykes formed a continuous wall to define (if not effectively defend) the liberties of the burgh. Beyond extended unfenced commonfield arable, with pasture and peatbog to support the burgh community. On the north side the burgh was originally defined by the Mosset Burn. And even after the Burn abandoned its medieval course, cautious burgh notaries conservatively continued to draft sasines by reiterating the descriptions contained in older deeds – defining feus by the old run of the river.
