DigVentures was appointed by the Rediscovering Ancient Connections Project Team of Pembrokeshire County Council to carry out geophysical surveys across four sites in Pembrokeshire. The sites comprised of Capel yr Hen Fynwent (SM 77581 28267), Llanrhian Church (SM 81932 31446), The Church of the Holy Martyrs at Mathry (SM 87930 32000) and Rosina Vallis / Hodnant Porthclais Caerbwdy (SM 74080 24410).

This report details the results of the geophysical surveys undertaken across these sites between the 17th to the 21st May 2021 (DigVentures Project Code ANC21), which form a second phase of works following surveys undertaken at St David’s in August 2020 (Roberts, 2020). The potential of these results to achieve the Aims and Objectives of the project are discussed in the final section of this report, along with recommendations for further investigation.

In format and content, this report conforms with current best practice and to the guidance outlined the Management of Archaeological Research Projects in the Historic Environment (Historic England 2015), the Research Framework for the Archaeology of Wales (Edwards et al 2017), the Chartered Institute for Archaeologists (2014), and the Europae Archaeologiae Consilium (EAC) Guidelines for the Use of Geophysics in Archaeology (Schmidt et al. 2016).

The work forms part of the Rediscovering Ancient Connections – The Saints project, which is a cross-border heritage and arts program. The program is 80% funded by the European Rural Development Fund and is led by Pembrokeshire County Council, with joint beneficiaries Wexford County Council, Pembrokeshire Coast National Park Authority and Visit Wexford.
