Castell Henllys is an Iron Age archaeological site in Pembrokeshire, Wales, notable for in situ roundhouse reconstructions and experimental archaeology. The site combines archaeological excavation, public interpretation, and living history to explore Late British Iron Age settlement patterns associated with Celtic communities and Romano-British contacts. Managed by a local trust and linked with regional heritage networks, the site contributes to Welsh archaeology, tourism, and environmental conservation.

History

The hillfort sits within a landscape shaped by prehistoric activity and later historical processes tied to Pembrokeshire Coast National Park, Dyfed, Celtic Britain, and the broader dynamics of Iron Age Britain. Archaeological narratives connecting the site refer to continental parallels in La Tène culture and insular developments studied alongside sites like Carn Euny, Bryn Celli Ddu, and Tre’r Ceiri. Scholarly discussion engages with themes from Roman conquest of Britain through the period of Sub-Roman Britain and regional shifts noted in records associated with Norman Wales and medieval Pembrokeshire manorial structures. Local land tenure histories intersect with administrative units such as Snowdonia National Park Authority-style frameworks and Welsh heritage policies influenced by institutions like Cadw and Historic England.

Archaeology and Excavations

Systematic fieldwork began in the 20th century and accelerated with projects linking to academic centres such as University of Wales departments, the British Museum research programmes, and collaborations with regional museums including National Museum Cardiff. Excavations uncovered defensive ditches, house platforms, pottery assemblages comparable to finds from South Wales and Severn-Cotswold contexts, and botanical remains utilized in interdisciplinary studies alongside specialists from Royal Botanic Gardens, Kew and palaeoenvironmental teams akin to those at University of Cambridge. Artefactual sequences brought together analyses using approaches developed by practitioners referenced in the literature from Council for British Archaeology and methods promoted by figures associated with English Heritage and experimental teams from University of Exeter. Radiocarbon dating linked stratigraphic sequences to broader chronologies debated in publications from Society of Antiquaries of London and case studies discussed at meetings of European Association of Archaeologists.

Reconstruction and Experimental Living History

The site is renowned for reconstructions of Iron Age roundhouses intended to replicate structural forms documented across Celtic Europe and British sites such as Hearth of the Iron Age exemplars. Rebuilding used traditional materials and techniques informed by research published in journals like Antiquity and implemented in collaboration with experimental projects associated with Butser Ancient Farm and practitioners from Experimental Archaeology networks. Living history programmes feature reenactors and craftspeople who draw on comparative evidence from sources including Tacitus for Roman-era contexts, and display technologies paralleled in reconstructions at Scotland’s brochs and Orkney Neolithic reconstructions. The experimental work informs debates about domestic architecture, fuel procurement linked to woodland regimes studied by Forest Research-style institutes, and subsistence strategies comparable to those modelled in studies from Oxford Archaeology.

Visitor Centre and Education

A visitor centre provides interpretation aimed at audiences from school groups to international tourists, incorporating curricula linked to institutions such as Welsh Government education initiatives and resources used by educators from University of Wales Trinity Saint David. Exhibits contextualise finds alongside comparative displays referencing artefacts housed in National Museum of Scotland and British Museum collections. Outreach programmes partner with local schools, community organisations, and networks like National Trust volunteers, and they host workshops drawing on craft traditions connected to regional cultural heritage celebrated at festivals like Eisteddfod and events organised by Pembrokeshire Coast National Park Authority.

Environment and Landscape

The site occupies a ridge in a mosaic of hedgerows, pasture, and semi-natural habitats within the Pembrokeshire landscape. Environmental studies integrate pollen analysis comparable to datasets held by Royal Society-affiliated projects and provide insights into woodland clearance, grazing regimes, and agricultural practices similar to reconstructions from Wetland Archaeology and Environment Research Centre initiatives. Landscape interpretation situates the hillfort in relation to coastal routes used since prehistoric times, drawing parallels with maritime links evidenced at St David's Peninsula, Cardigan Bay, and exchange networks discussed in research involving the Institute of Archaeology, UCL.

Conservation and Management

Conservation and site management balance public access with protecting archaeological deposits, guided by principles championed by ICOMOS and policy frameworks recognizable in listings administered by Cadw and advisory input from organisations like Natural Resources Wales. Ongoing stewardship includes vegetation control, structural maintenance of reconstructed buildings, and monitoring informed by methodologies from Historic England conservation practice. Collaborative management involves local authorities, heritage charities, and funding mechanisms similar to grants from heritage funds administered in partnership with bodies such as Heritage Lottery Fund and regional trusts. The site remains a case study in integrating research, education, conservation, and community engagement within Welsh heritage landscapes.
