Clwyd-Powys Archaeological Trust

The Clwyd-Powys Archaeological Trust (CPAT), also known in Welsh as Ymddiriedolaeth Archeolegol Clwyd-Powys or YACP, was a regional archaeological trust serving north-east and mid-Wales. Established in 1975, it was one of four Welsh Archaeological Trusts created to provide a permanent regional framework for archaeological investigation, conservation, interpretation, and advice. The organisation developed from the Rescue Archaeology Group established in 1970, an initiative associated with archaeologist Christopher R. Musson. Musson became CPAT's first chief executive and directed the organisation during its formative period. CPAT combined charitable, educational, advisory, and commercial functions. Its principal responsibilities included maintaining the regional Historic Environment Record (HER), advising local authorities and developers on the archaeological implications of planning proposals, delivering heritage-management projects, and undertaking field investigations. Its field-services portfolio included desk-based assessments, historic-environment characterisation, site evaluations, excavations, surveys, and work responding to threats to archaeological remains. The Trust was also a Registered Organisation with the Chartered Institute for Archaeologists. The Trust's early work included important investigations of prehistoric and later monuments in Powys and the wider region. Excavations at the Breidden hillfort addressed damage caused by quarrying, while work at Collfryn examined a late Iron Age hillslope enclosure with evidence of changing settlement organisation, roundhouses, and probable granary structures. CPAT also contributed to research and management involving Offa's Dyke, Wat's Dyke, Hen Domen near Montgomery, Roman roads, Roman and later settlement in Deeside, upland landscapes, and the Walton Basin or Hindwell area. From the 1990s, as archaeological work became increasingly linked to the planning system, CPAT expanded its contract archaeology and development-led services. This complemented rather than replaced its public role. The organisation continued to maintain the regional HER, provide planning and conservation advice, and run educational and outreach activities. Outreach included public events, community archaeology, and projects intended to engage communities experiencing social or economic exclusion. Partnerships included work with the National Trust and the Clwydian Range and Dee Valley Area of Outstanding Natural Beauty. CPAT also acted as a custodian of archaeological sites. In 2008 it acquired Beacon Ring, a hillfort on the Long Mountain near Welshpool, to help protect its earthworks. Later investigations examined the ramparts, entrances, and a central mound. Excavation in 2020 indicated that the mound was probably the location of a post-medieval beacon rather than a prehistoric burial mound; it was later reused as an Ordnance Survey triangulation point. CPAT was structured as both a limited company and a registered charity. Its voluntary Board of Trustees delegated daily management to the Director, who also served as chief executive. In September 2023 the four Welsh Archaeological Trusts agreed to merge. The merger took effect on 1 April 2024, when CPAT and the other regional trusts became part of Heneb: the Trust for Welsh Archaeology. CPAT therefore ceased to exist as an independent legal and organisational entity, while its regional functions continued through a Heneb office.

CPAT originated in the rescue-archaeology movement of the early 1970s. The Rescue Archaeology Group, established in 1970 and associated with Christopher R. Musson, sought to respond to the destruction of archaeological sites through quarrying, development, agriculture, and other modern pressures. In 1975 the group developed into the Clwyd-Powys Archaeological Trust, one of four regional trusts established across Wales. The Trust's regional remit covered the historic counties and landscapes broadly associated with Clwyd and Powys. Its initial fieldwork demonstrated the value of combining emergency investigation with longer-term regional research. Excavations at the Breidden hillfort in Powys addressed damage from quarrying, while work at Collfryn examined a late Iron Age enclosure whose evidence included settlement remodelling, roundhouses, and structures interpreted as probable granaries. CPAT later contributed to investigations of medieval monuments including Offa's Dyke and Hen Domen near Montgomery, as well as projects concerning Roman roads, Roman and later remains in Deeside, upland landscapes, and the Walton Basin or Hindwell area. A defining institutional contribution of the Welsh Archaeological Trusts was the development of Historic Environment Records. During the 1970s Wales pioneered a national network of what were then commonly called Sites and Monuments Records. These records brought together information about archaeological sites, historic buildings, landscapes, finds, and investigations, eventually using computerised systems to support research, conservation, and planning. CPAT maintained the regional record for its area and made historic-environment information available to public authorities, professionals, researchers, and the wider public. The Trust's operating model changed as public funding arrangements evolved. During the 1980s archaeology benefited from significant government support, including support associated with the creation of Cadw in 1984. Later reductions in labour-market and manpower-based funding encouraged a shift toward development-led archaeology. During the 1990s CPAT expanded its commercial contract work, undertaking assessments, evaluations, excavations, surveys, and archaeological monitoring connected with planning and construction. It retained its charitable and educational purpose while developing a professional service role for developers, local authorities, landowners, and public bodies. CPAT was organised around three main areas. The Historic Environment Advisory Service maintained the HER, offered planning advice, and undertook heritage-management work. The Education and Outreach team delivered public events, learning activities, and community projects, including initiatives aimed at communities affected by social and economic exclusion. The Field Services team delivered archaeological projects for public- and private-sector clients, from characterisation and survey to evaluation and excavation. This combination gave the Trust a role spanning discovery, recording, decision support, conservation, interpretation, and public engagement. During the 2010s the balance of fieldwork moved from large thematic investigations toward more site-specific development-led projects. This broadened CPAT's work across Wales and, in some cases, neighbouring parts of England. At the same time, it diversified the funding and partnerships supporting public archaeology. Long-running relationships with the National Trust and the Clwydian Range and Dee Valley Area of Outstanding Natural Beauty supported public interpretation, landscape research, and community participation. In 2008 CPAT purchased Beacon Ring, an Iron Age hillfort on the Long Mountain near Welshpool, to safeguard its earthworks. Investigations in 2018 and 2019 focused on the ramparts and entrances. A 2020 excavation investigated the central mound, which earlier interpretations had associated with a prehistoric burial. The evidence instead suggested that it was probably the site of a later beacon, subsequently reused by the Ordnance Survey as a triangulation point, including a 1948 installation. Legally, CPAT operated as both a limited company and a registered charity. Its trustees were voluntary, non-executive directors who delegated daily management to the Director. In September 2023 the four Welsh Archaeological Trusts agreed to merge. On 1 April 2024 the merger was completed through Heneb: the Trust for Welsh Archaeology. The former trusts became regional offices within Heneb, CPAT's independent trusteeship ended, and the CPAT legal entity ceased to operate as a separate organisation.
