In this, the centenary anniversary of the armistice, Gwynedd Archaeological Trust has been running a First World War recording project. Funded by Cadw, and with the help of volunteers, we've been recording Gwynedd's First World War memorials and memorialisation.

Join us on Sunday 4th November 2018 (10:00am – 4:00pm) at Menai Bridge memorial hall for our special open day. You'll be able to find out more on the project as well as view a photographic exhibition of some of the poignant images we've captured so far. You don't have to book a place, just pop in. Free tea and coffee.

The open day will also feature Menai Heritage's ‘Menai Heritage and World War I' community project. Supported by the HLF, this project focused on the effect the Great War had on the people of Menai Bridge.

There's limited on-street parking adjacent to the memorial hall, therefore we suggest you might want to consider other parking options around the town (please note – some of these car parks are pay and display).

We're also running two guided walks on the day, visiting the First World War memorial on nearby Church Island. If you'd like to join us for either of the guided walks you'll need to book a place – to do so please contact Dan Amor 01248 366970.

Information on our wider First World War project

David Hopewell awarded the GT Clark prize for his work on Roman sites in North Wales

David Hopewell, a senior Archaeologist at GAT was presented with the 2018 G.T.Clark prize by the outgoing chairman of the Cambrian Archaeological Association Professor Prys Morgan. The prize was for “quality in published work on the Roman archaeology of Wales and the Marches”.

This was in acknowledgement of many important discoveries made during a comprehensive Cadw grant-aided resurvey of the majority of Roman sites in Gwynedd and beyond using geophysics, community excavation, and field survey. In addition two ground-breaking sites were discovered and investigated; a Roman settlement at Tai Cochion and a fortlet at Cemlyn Bay (both on Anglesey).

The results have been published in three academic papers in Britannia, one in Archaeologia Cambrensis, a book “Roman Roads in North-West-Wales” and also in the standard textbook on Roman Wales "Roman Frontiers in Wales and the Marches". 

The award also acts as an acknowledgement of an often overlooked aspect of the Welsh Archaeological Trusts' work, namely the production of large amounts of important new information all of which is made accessible to the public either via the Historic environment record or/and in publications.  This forms the basis for ongoing research in many aspects of the history and heritage of Wales.

Portable Antiquities Scheme

The Portable Antiquities Scheme Cymru / Wales is a project to encourage the voluntary recording of archaeological objects found by members of the public in Wales. Every year many thousands of objects are discovered, many of these by metal-detector users, but also by people whilst out walking, gardening or going about their daily work. The Gwynedd Archaeological Trust provides a service to record the objects found in North West Wales by members of the public, whether resident or on holiday in the area.

If you would like to bring in objects for identification and recording please contact Jane Kenney to arrange a mutually convenient time. Jane Kenney can be contacted by emailing or ringing 01248 366959.

Jane Kenney will be away for all of April, so please contact her in May for PAS enquiries.

If you think you have a Treasure Case for the Portable Antiquities Scheme, please contact the PAS Finds Liaison Officers for Wales directly for them to assess the case. Mark Lodwick 02920 573226 or Susie White 01978 297466

Mae dwy garreg o'r Canol Oesoedd cynnar newydd eu darganfod yn ymyl Pentre Berw ar Ynys Môn.

Tra allan yn cerdded, sylwodd Maredudd ap Rheinallt o Fangor ar garreg unionsyth gyda llythrennau arni, a chysylltodd gyda'r Ymddiriedolaeth yn ei chylch. Wedi ymweld â hi, daeth staff yr Ymddiriedolaeth i'r casgliad ei bod yn esiampl o garreg arysgrifedig o'r Canol Oesoedd cynnar. Cafodd yr Athro Nancy Edwards o Brifysgol Bangor wybod, ac mae hi wedi cadarhnau bod y garreg yn esiampl dda o gofeb arysgrifedig o'r 6ed ganrif. Mae'r llythrennau'n rhedeg mewn dwy linell fertigol i lawr wyneb y garreg. Er fod peth difrod, gellir darllen enw personol merch, ‘VOTEPA,' ar y linell uchaf, ac ar yr ail linell gellir gweld ‘IACIT' sydd yn golygu ‘yma gorwedd'.

Yng nghwmni'r archaeolegydd Frances Lynch Llewelyn, ymwelodd staff yr Ymddiriedolaeth â'r garreg, ac yn ystod yr ymweliad, sylwodd Frances ar garreg arall. Ar hon hefyd roedd llinellau endoredig. Fe'i dehonglwyd fel croes endoredig yn dyddio o'r 12fed ganrif. Mae'n cyfateb â nifer o groesau yn dyddio o'r 9fed i'r 12fed ganrif sydd wedi eu darganfod yn yr ardal, ac mae'n awgrymu bod ysgol lwyddiannus o grefftwyr lleol yn gweithio yn ne—orllewin Môn. Gellir darganfod esiamplau o groesau o'r cyfnod hwn yn eglwysi Llanfihangel Esceifiog, Llangaffo a Llangeinwen.

Cewch fwy o newyddion wedi cwblhau mwy o waith ymchwil ar y cerrig.



Two new early medieval stones have been found on Anglesey, close to Pentre Berw.

Maredudd ap Rheinallt of Bangor reported to the Trust an upright stone with lettering running down the stone which he had spotted whilst out walking. Further visits by Trust staff led to the belief it was an example of an early medieval inscribed stone. Professor Nancy Edwards of Bangor University was informed, and she has confirmed that the stone is a good example of a 6th century inscribed memorial. The lettering is in two lines running vertically down the stone. Though slightly damaged the top line can be read as a personal female name ‘VOTEPA', and the second line as ‘IACIT', meaning ‘here lies'.

Whilst visiting the stone with the archaeologist Frances Lynch Llewellyn, Frances spotted a second stone, on which were incised lines. These were soon interpreted as an incised cross of 12th century date. This compliments several crosses found within the area of 9th to 12th century date, and suggests a flourishing local school of craftsmen working within south-west Anglesey. Examples of crosses of this date can be found at the churches of Llanfihangel Esceifiog, Llangaffo and Llangeinwen.

We will keep you informed of any news about the stones as they are further investigated.

New Roman Road Find

There has been much debate over the years about the route of the Roman road running south from the fortlet at Brithdir to the fort at Pennal. Most published accounts trace a rather long route following the Ffordd Ddu to the west of Cader Idris. Recent evidence from an Environment Agency lidar survey showed a long straight feature to the south-east of Dolgellau, near Cross Foxes, that suggested that the Roman road actually ran to the east of Cader Idris. Gwynedd Archaeological Trust and a group of volunteers have just completed an assessment excavation and have discovered that the feature seen on the lidar survey is a very well-preserved length of Roman road running through peat bogs to the west of the modern road. The road is a typical Roman construction being 5.5 to 5.7m wide with a slightly cambered agger (raised causeway) with a compacted clay and gravel surface and small drainage ditches to either side.

Roman Roads in North-West Wales by David Hopewell

Roman Roads in North-West Wales is a new publication by Gwynedd Archaeological Trust. It describes the results of a ten-year project that has reassessed all of the evidence for Roman roads in the region and has resurveyed the known surviving portions. The book incorporates evidence from well over a hundred years of previous work by a wide range of researchers, as well as the results of the Trust's Cadw grant-aided Roman roads project and the latest discoveries from geophysical and Lidar survey. The book examines the distinctive archaeology of Roman roads in the upland regions. These are very different to the well- known roads running in straight alignments through the lowlands of England but are still recognisably Roman. The book is well illustrated and carefully referenced and should appeal to newcomers to the subject and experienced researchers alike.

The author, David Hopewell is a Senior Archaeologist at Gwynedd Archaeological Trust. He has published both academic and popular articles on a wide range of archaeological topics and specialises in the archaeology of Roman Wales and geophysical survey.
