Welcome to Discovery and Learning. This booklet briefly describes some of the work that the Glamorgan-Gwent Archaeological Trust has carried out in the past year. We hope that this will provide a stimulus for you to explore the diversity and richness of the historic environment in South Wales.

The preservation of the historic environment depends on a consensus of support and appreciation of value by all of us. Two of the projects, Gelligaer Common and Arfordir, briefly described in these pages, provide examples of how the Trust is actively engaging communities in investigating and recording their local heritage. Other pages show how rich our shared heritage is, and in the case of Ynysfach Ironworks describe the remains of a great Welsh industrial innovation and how much that was thought to have gone can still survive.

I hope that you can make your own journeys of discovery.

When the Register of Landscapes of Special Historic Interest in Wales was published in 2001, it included Gelligaer Common because it was 'a rare...upland landscape' which 'represented continuity of land use and activity from the prehistoric period to the recent past'. However, it's only over the past year that we have come to realise just how long the continuity has lasted, and how rare for Wales is some of the archaeology.

A prehistoric sacred mountain at Gelligaer

Last August we led a walk to introduce members of Groundwork Caerphilly to the archaeology of Pen Garnbugail - the highest summit on the common - and the area on its eastern side. This is the part of the common where archaeological sites are thickest, with Bronze Age burial cairns and cairnfields, the Roman road between the forts at Gelligaer and Brecon Gaer, and medieval platform houses and field boundaries. It was while we were walking between the cairns on the eastern slopes of Pen Garnbugail and the platform houses at Coly Uchaf that one of the people from Groundwork Caerphilly spotted that there was a cup-mark on one of the rocks. It seemed too good to be true, so we sent pictures off to Dr George Nash of Bristol University, who is an expert on rock art. He was enthusiastic too, so we thought that it would be a good idea to see whether there was more rock art to be found on the common and put a proposal to Cadw to carry out a community archaeology survey to look for it. Cadw was quite keen too, but couldn't give us any funding until the end of the financial year. So in March, the Trust and Groundwork Caerphilly assembled a bunch of volunteers and we went off to see what we could find.

Obviously, in the couple of weeks we had available we weren't going to be able to cover the whole of the common, so we concentrated our efforts on Pen Garnbugail and the area immediately around it. All in all, we made a systematic search of about one sixth of the area. This search didn't actually produce any rock art, although we did record a small standing stone associated with the Coly Uchaf cairnfield that had been missed during earlier examinations of the site. However, two of our volunteers told us about a carving on Bryn yr Hebog on the eastern side of the common. This has a group of markings consisting of three small cup-marks and a crescent, and then a single cup-mark on another part of the stone. This looks very authentic too, although we still need to have it definitively confirmed.

The discovery of all these cup-marks is very exciting. Although rock art is common in some parts of the British Isles, such as the northeast of England, very little has been found in Wales. In Glamorgan we have Maen Cattwg just outside Gelligaer village. We also have a few other places where pieces of rock with cup-marks have been found - one that had been built into the Simondston cairn excavated by the National Museum of Wales near Bridgend just before the start of the Second World War, another stone found in Bargoed in the 1930s, and two recently spotted on Mynydd Marchywel just north of Neath. So our two new pieces are a significant addition.

The other interesting thing is the date. Cup-marks are Neolithic, so that shows that people were visiting the ridge at Gelligaer thousands of years earlier than we originally thought. We have always known that it was a special place in the Bronze Age, because of all the cairns. We think it was a sacred mountain, one of the spiritual places of Bronze Age South Wales. It now looks as though Bronze Age people were merely carrying a tradition that had started thousands of years before, when people first started to leave a permanent mark on the landscape.

RIGHT: We went to look at MaenCattwg at the start of the project,so we would know what to look foron the common.

The four Welsh Archaeological Trusts have been working with Cadw for more than ten years on a review of all known monuments in Wales. After having completed the prehistoric and Roman periods, we are now dealing with those in later periods. A preliminary study of medieval and early post-medieval sites carried out in 2010 showed us where the main gaps in our knowledge were. Subsequently, Cadw gave us grants to look at monastic sites, abandoned chapels and churches, holy wells and some of the sculpture associated with medieval churches, to assess them and look at ways in which they could be protected for the future.

‘A landscape white with churches’

It is only recently that the monastic remains at Goldcliff Priory were plotted from air photographs. This project gave us an opportunity to examine the earthworks at ground level. At Llanfair Cilgoed, the Victorian church stands next to the remains of a monastic grange, complete with chapel. There has been some archaeological work here, but more could be done. A particularly interesting little church was St Andrews Minor near Llandow in the Vale of Glamorgan. Unlike its much larger cousin St Andrews Major just outside Barry, this parish church went out of use at a relatively early date and survives as a tiny little box of a building, nearly up to roof level. Around it are the earthworks of the churchyard and the village whose abandonment meant that there was no further use for a church.

‘A landscape white with churches’

Some of the most interesting carvings were originally part of medieval churchyard crosses. At Llantrithyd we looked at a decorated stone that might originally have been the base for a Norman cross - if this is the case, it is extremely rare in Glamorgan. Another rare survival is the head of a cross carved with the Trinity on one side and St Leonard on the other. Surprisingly, we found this at the Victorian church at Pen-y-fai near Bridgend where it had been moved possibly from Newcastle church, which was dedicated to St Leonard in the Middle Ages. Another possibility is that it might have been from a wayside cross, which would make it a unique survival in the county.

We looked at ways in which to investigate these monuments, conserve them and present them to the public, for example through a combination of information panels and heritage trails. At some sites there is scope for projects with community involvement. At some major monastic sites, such as Goldcliff Priory, Grace Dieu Abbey, Llantarnam Abbey, and Margam Abbey, geophysical, topographic survey, and field walking would give us a greater understanding of the extent and nature of surviving remains within their precincts. In a few cases, we have recommended small, carefully positioned excavations to confirm details of buried remains.

YnysfachIronworks

Parts of the Ynysfach Ironworks have been excavated by the Trust ahead of the construction of a new building at Merthyr Tydfil College. The principal buildings we uncovered were the southern engine house and associated chimney and boiler house, a casting house, and, uniquely for surviving Welsh iron processing centres, a well preserved refinery building.

Ironworks.

The Ynysfach Ironworks opened in 1801 under the ownership of the iron-master Richard Crawshay. In the first half of the nineteenth century it was used to smelt and refine iron whereas, its larger partner, Cyfarthfa Ironworks located less than 1km upstream of the River Taff and also owned by Richard Crawshay, was concerned with puddling and rolling the metal. The refining process undertaken at Ynysfach was also known as the Welsh process. This involved converting grey cast iron into wrought iron of the very highest quality. It is likely that the Ynysfach Ironworks were purpose built by Richard Crawshay for this process.

Page 15: Discovery & Learning 2012

Excavations at Ynysfach Ironworks

The early phase of the refinery building was also built in Crawshay's monumental tradition. It would have housed only two refining furnaces - a reflection of the production capacity of the blast furnaces and single casting house. The later expansion of the ironworks meant that the demand on the refinery increased and it was extended to support six refining furnaces.

monumental style of building is

This first phase of building work undertaken by Crawshay comprised a twin blast furnace, a single (northern) engine house and a boiler house complex with chimney stack, plus a small refinery. A significant expansion to the works at Ynysfach came in 1839 when Richard’s grandson William Crawshay II (1788-1867) built two additional blast furnaces and associated casting houses. A second (southern) engine house and a significant extension to the refinery building was also made. This expansion was clearly seen in the excavated remains of the site.

Our excavations exposed the remains of the southern engine house, boiler house, chimney complex and the refinery. In places the walls survived to a height of more than 2 metres. Many of the Crawshay's industrial buildings were constructed in a monumental style, and this is the case at Ynysfach, where the well-dressed stone buildings were finished with cut limestone quoins and arches.

Excavations at Ynysfach Ironworks

Although none of the furnaces survived, it was clear where they would have been positioned and the remains of all six of the furnace bases and brick run-out bays were revealed during the excavation. Each furnace would have been fixed upon large stone and brick bases which joined to a run-out bay. These run-out bays would have held large iron water-holding troughs, one of which was found in-situ. Fitting neatly on top of this large trough would have sat a shallower trough to hold the refined metal as it flowed out of the refining furnace. The large tank below would have held water to cool and solidify the metal above ready for breaking up into manageable pieces, before being sent by canal boat, and later by tram, to Cyfarthfa Ironworks for further processing.

A complex of brick and stone built drains surrounding the run-out bays was excavated and these would have ensured both a cool water supply to the cooling troughs and the rapid removal of the water to the nearby canal once the water had been used in order to avoid potential explosion if it was left to collect around the furnaces. In the early phase of the works these drains were capped by stone, and later by large iron plates.

Contrary to popular belief, Wales was not a quiet backwater during the conflicts of the 20th century. Because it was so far from the Continent, it was ideal for many support operations. These included manufacturing, maintenance and storage of armaments, military training, and research and development, including weapons testing. The military installations included many airfields, which developed distinct functions and purposes giving each its own unique character. Fighter stations defended the industrial towns and the docks that were targets for German bombers. Training and storage units, which were tasked with the reception, storage and despatch of RAF aircraft, covered large areas of the landscape.

As part of a study of WWII sites across the whole of Wales, Cadw has funded us to survey and record eight airfields. All of these stations were planned in accordance with requirements, first laid down in 1914, that fabric must be dispersed to limit the damage if they were attacked. If necessary, functions could be switched from a damaged installation to another one on a different part of the airfield.

“The gratitude of every home in our Island, in our Empire, and indeed throughout the world, except in the abodes of the guilty, goes out to the British airmen who, undaunted by odds, unwearied in their constant challenge and mortal danger, are turning the tide of the World War by their prowess and by their devotion”. Winston S Churchill, August 20th 1940, House of Commons.

Recording Second World War Airfields

Airfields were divided into the separate functional areas of flying field, domestic sites and technical sites. In the Second World War, they were also provided with close defences in the form of pillboxes and battle headquarters. Our survey showed that, at some of them, original structures still remained in spite of the way the airfields had been used for other purposes after the war. At RAF Rhoose, now Cardiff International Airport, a Robin-type hangar still survives, now used to house small light private aircraft belonging to the Cardiff Aero Club. Although this was a common type of hangar during the Second World War, this example is thought to be the only one now left in Wales.

Recording Second World War Airfields

Alongside our other modern airport, near Swansea, there are also interesting survivals from when it was RAF Fairwood Common, a forward airfield for night fighters. The Flight Office not only provided office accommodation for flight commanders and flight sergeants, but also included pilots' rest rooms, storerooms and locker rooms. Sleeping shelters were built to accommodate 33 men of each flight assigned on night scramble duties, and were located close to the aircraft fighter pens so that during an emergency pilots did not have far to run to get to their aircraft. The internal space is divided into six bays, with two bunks per bay. The bunks still have their wooden frames though the wooden slats have been lost, and in one shelter the frames still have stencilled letters defining where each airman slept.

The 'Arfordir' project has been set up to get local communities along the Welsh coast involved with monitoring change to eroding archaeological sites and recording these and new exposures where they are under particular threat. Coastal areas have been a focal point of human activity for thousands of years, and the coast of South Wales includes sites dating from early prehistoric times to the present day.

Arfordir: Monitoring and recording our eroding coastland

The earliest sites include caves inhabited before the Severn Estuary and Bristol Channel were formed at the end of the last Ice Age. In the Neolithic and Bronze Ages the coast extended much further out than it does today and was occupied by small settlements linked by wooden trackways. Later on in the Iron Age some of the promontories along the coast were fortified and some of these were re-occupied by the Romans and also people living in South Wales after they left. Trade has always been important to the South Wales economy and there are many wrecks on the coastline as well as the remains of ports, harbours, landing places and defensive sites. Other remains, such as fish traps, are connected with exploitation of natural resources.

Arfordir: Monitoring and recording our eroding coastland

It would be impossible for existing agencies to monitor the constant change. However, with training, volunteers have already been able to make important contributions to the understanding, recording, and protection of our coastal heritage. Those who visit their coastline regularly are already familiar with the landscape, and are perfectly placed to help us. So far we have supported the establishment of groups working in Gower, Swansea Bay, and around Margam, Kenfig and Merthyr Mawr. In 2012 we will be expanding the programme along the Vale of Glamorgan coastline to Penarth and Barry.

The South Wales coastline is varied with many different environments: saltmarshes; sand dunes; peat shelves; cliffs. It is very vulnerable to erosion. The causes can be both natural (including climate change), and human - some of the things we do can have severe impacts on these sometimes very sensitive environments and archaeological remains.
