Focus on Ormond Castle, Avoch, Ross-shire

The North of Scotland Archaeological Society (NOSAS) and Avoch Community Archaeology (ACA) group joined forces in March 2016 to survey and photograph Ormond Castle, GR NH 6963 5358 (HER ID: MHG8226, Canmore ID: 13572). The castle overlooks the village of Avoch on the Black Isle and commands good views across the Moray Firth to the south and the former ferry crossing between Chanonry and Ardersier in the east.

To date Ormond castle has not received the attention it deserves. It is traditionally associated with William the Lion (1143 – 1214). He built two castles on the Black Isle in 1179, one at Redcastle and a second which is thought to be this one. Andrew de Moray was owner of the castle in the 13th century and principal commander of Scottish forces in the north during the Wars of Independence in the late 13th Century, but was mortally wounded fighting alongside William Wallace at the Battle of Stirling Bridge in 1297. In 1455, after being in the hands of the de Moray family and the earls of Ross, the castle passed to royal control and in 1481 James III granted it to his son, the Marquis of Ormond, from whom the present name derives. The castle was destroyed by Cromwell’s forces in 1650 and the stones were transported over the firth to build the Citadel in Inverness.


Only the foundations of the walls remain today. The HES scheduling document for the site states that “the monument is of national importance because it is a fine field monument of a type rare in Scotland; it is said to have been one of the royal castles built c.1179 and …… the clearly defined remains have the potential to increase understanding of 12th century fortification techniques and military history.” Also of interest are the ditches and banks around the northeast side of the site, reminiscent of those found on some Iron Age forts and suggesting the possibility of the site having had earlier occupation.


In 1883 the castle was investigated by Angus Beaton (see his notes in PSAS), but the excavations carried out remain unpublished and the plan produced was inadequate. A further sketch was drawn in the 1960s, but it too is not very detailed and does not give an indication of the complexity of the site. Our task to carry out a measured survey using planetables was ambitious; not only was the site complex, but it was also big (150m x 65m), covered in thick vegetation and had considerable height discrepancy.

The local ACA folk were enthusiastic making a good job of clearing the vegetation and on a calm but cold weekend in March 20 people, from both NOSAS and ACA, gathered at the site. Many had no experience of using a planetable but, after some training, they quickly got into the way of it and the task was completed in 2 days using 5 planetables. Nine PT stations were needed to cover the site and these were carefully linking together on the drawings. Inevitably the height variations meant that the PT positions were not quite correct in their relationship to each other, but this was overcome by making adjustments at the “drawing-up” stage of the plan using the processed aerial photographs taken from a quadcopter flyover on the second day.


The flyover also produced some impressive 3D images of the castle  and its features which gave a greatly enhanced overall picture of the fortification (see video below). These images also revealed a few more features which we were able to fill in “by eye” on the two return visits which were needed to verify and adjust the drawing.

This survey was only part of the first non-invasive phase of the Avoch Community group project; we wish them all the best with their future plans and look forward to working with them again.
