INTRODUCTION 1.1 General 1.1.1 This report presents the results of a programme of archaeological excavation and recording carried out by CFA Archaeology Ltd (CFA) in advance of construction works associated with the A832 Achnasheen to Kinlochewe Phase 3 road upgrade, between Glen Docherty viewpoint and Kinlochewe, Highland (NGR: NH 030 619 - 064 594; Fig. 1). The work was commissioned by The Highland Council Transport, Environmental and Community Services (TECS). 1.1.2 The requirement for the archaeological recording formed a condition attached to planning consent for the proposed road upgrade scheme (Ref: 04/969/NIDRC & 05/00164/FULRC) by the Archaeology Unit of The Highland Council Planning and Development Service. In May 2005 CFA produced a Written Scheme of Investigation (WSI) for the recording works (Appendix 6) to fulfil the requirements of the Brief and schedule, which was approved by The Archaeology Unit. 1.1.3 The objectives of the archaeological recording were to: • record to agreed methods and appropriate standards those archaeological features that lay within areas proposed for development, prior to the commencement of construction works, and • ensure that the needs for archaeological recording and conservation were met without causing any unnecessary delay or disturbance to the road improvement project. 1.2 Planning Background 1.2.1 In 2001 The Highland Council commissioned CFA Archaeology Ltd to conduct a baseline survey of the proposed Phase 2 and Phase 3 A832 road upgrade corridor between Lubmore and Kinlochewe, based upon a preliminary route alignment design. The survey was conducted to fulfil the requirements of a Specification produced by the Archaeology Unit. A report detailing the results of that study (Dunwell 2001) has been lodged with the Council’s Sites and Monuments Record. 1.2.2 In 2004 the relevant baseline data gathered during the 2001 study was incorporated into an Environmental Statement for the proposed Phase 3 road upgrade scheme. In 2005 additional survey work was undertaken over an area at Bruachaig to the north of the proposed road upgrade which is proposed for agricultural improvement. This area is proposed for use to deposit surplus material excavated during the Phase 3 road upgrade. The additional work led to the identification of three further sites. 1.2.3 Both documents contained mitigation recommendations that were used to form the WSI for this phase of the development.

ARCHAEOLOGICAL BACKGROUND 2.1 General 2.1.1 Baseline desk-based assessment and field survey conducted in 2001 and 2004 identified 41 sites of cultural heritage significance along a study corridor including the proposed road upgrade corridor between Glen Docherty viewpoint and Kinlochewe and an area at Bruachaig (sites are catalogued in Dunwell 2001 and Dunwell 2005). Prior to the baseline survey the National Monuments Record of Scotland (NMRS) had recorded eleven sites within the study corridor, including shielings (Ref: NH05NE 7), the site of an iron- working bloomery, enclosure and structure (Ref: NH06SE 8), Glen Dochart settlement (Ref: NH06SE 9) enclosures (Ref: NH06SE 10), a structure and wall (Ref: NH06SW 11), iron-working bloomery (Ref: NH06SE 1), Kinlochewe Lodge (Ref: NH06SW 13), Kinlochewe Bridge (Ref: NH06SW 5) and various old road alignments (Ref: NH05NE 6 and NH06SW 15). The baseline survey demonstrated that most of the significant archaeological sites and monuments identified by the study could be related to one of three principal factors influencing the historic development of the landscape: • Medieval or later agricultural settlement and land use. • The construction of the military road in the 18th century, and its subsequent upgrading and realignment to form the modern road. • The development of the medieval or later iron-working industry. 2.1.2 The following sections introduce the results of the baseline survey, summarising the text included in the Cultural Heritage chapter of the Environmental Statement (ES) produced for the Phase 3 scheme, but focussing upon those remains that required archaeological recording in advance of road upgrade construction works. Detailed baseline survey descriptions for examined sites are included in Sections 5-18: for other sites see Dunwell 2001 and 2005. 2.2 Old road alignments 2.2.1 A road has connected Achnasheen and Loch Maree since the mid 18th century, and it is quite possible that earlier droving routes existed. Cartographic and documentary evidence indicate that since then a complex sequence of re- alignments and improvements to the road line have taken place. Roy’s map of 1747-55 records what may be an original military road, forming part of a road connecting Contin and Poolewe. That road for the most part followed broadly the same route as the current A832. However, at the foot of Glen Docherty, the early road crossed Abhainn Bruachaig and headed northwest, to the southwest of the proposed surplus excavated materials disposal site at Incheril and along the east side of Loch Maree. No formal road crossing Glen Docherty Burn and heading west to Kinlochewe appears to have existed until the early 19th century.
