The Bronze Age – 2,500 – 500 BC

  • Copper Age / Beaker Period: (2,500 – 2,000 BC)
  • Bronze Age Proper: 2,000 – 500 BC
  • Early Bronze Age: 2,000 – c. 1,500 BC
  • Middle Bronze Age: c. 1,500 – c. 1,200 BC
  • Late Bronze Age: 1,200 – 500 BC


1. The Copper / Beaker / Gold Period (2,500 – 2,000 BC)

This period is chiefly defined by the appearance of new technology;

  • Copper artifacts such as axes, awls (used for boring small holes in leather or wood) and daggers
  • Beaker pottery
  • Stone artifacts, including barbed and tanged arrowheads

The copper from the southwest of Ireland was traded throughout Ireland and Britain, these have produced some of the earliest dates for copper in northwestern Europe.

Copper technology was in other countries long before it reached Ireland. For example;

  • 7,000 BC in Iraq and Iran
  • 4,000 BC in the Balkans
  • 3,000 BC in Spain & Portugal
  • 2,500 BC in Ireland

But there was a trading of ideas and technology between countries, especially across the Atlantic seaboard. This can be seen in the use of passage tombs (4,000-3,500 BC). They are found in Ireland, Britain, Portugal, Spain, France, Germany, Denmark, Sweden and Poland. We have also evidence of rock from Tievebulliagh in Northern Ireland being found throughout Britain.

Beaker Pottery

This type of pottery appears at the start of the Metal Ages.

Where it is found?
About 2,400 BC it is found in Ireland, Portugal, Denmark, Czech Republic, Hungary and Sicily. Metals appear in these areas about the same time. It is most likely that Beaker pottery was being made locally and it would be too difficult and fragile to transport over long distances. In Ireland it is mainly in megalithic tombs above the Galway-Dublin line. Broken pieces of it were also found with domestic refuse at Ross Island – were these people wealthier? We don’t know.

What is distinctive about it?
Beaker pottery was also much more decorative than the Neolithic pottery. The use of pinched rolls, the ‘s’ shape and the use of cord impressions are common throughout Europe.

Where did it come from?
Reference to the ‘Beaker Folk’ spreading across Europe is a myth that was probably based on the Roman invasions. As with the spread of Christianity, the ideas and technology spread. As previously said, it was made locally.


Was the mining successful? Yes. The high arsenic content and the presence of other trace elements has given us ‘finger-prints’ which allow us to show that copper objects found in Britain are made from Irish copper. The routes for trading stone axes were long established. These routes were now used to trade metals.

How was the copper mined? Fires were lit against the rock and water thrown on the hot rock to cause it to splinter. The copper ore was then clipped off and put in a fire made up of alternative layers of copper and charcoal, heated up to 1,200°C. In the 19th century these mines were called Danish or Viking mines (hee haw!)
Where was copper found in Ireland? At Ross Island, Mount Gabriel in County Cork, south Waterford, Avoca in Wicklow, Tipperary and Connemara.

How did copper technology come to Ireland? Most likely it came from Spain and Portugal and possibly Central Europe. Some things could have been learn accidentally or from experience, such as, that the addition of arsenic to copper makes it harder. Up to the 1980’s it was documented that the Celts brought metal technology to Ireland to the ‘ignorant locals’. This stems from English archaeologists in the 18th and 19th century, partly to justify themselves being here.

1. We can see the progression of the design of axes by the introduction of flanges and more elaborate designs coming from the moulds.
2. The potters wheel appears about 0-500 AD / 3. from 600BC – 1100AD there is no evidence of pottery in Ireland
3. Copper cannot be forged, it must be shaped in a mould.
4. The use of fire in mining had existed for a long time, it had been used in Stone Age factories and in the making ceramics.

1. A point worth remembering is that the use of metal only dates back 10,000 years whereas the use of stone dates back million of years.
2. The average Irish Neolithic person was living in better housing than the average 19th century Irish person.

Gold in Ireland

There are about 130 sites that we know of where gold occurs. However, in the majority of these the gold occurs in bedrock and probably was not accessible to Bronze Age man. It is more likely that he got his gold as nuggets and flakes in the sands of rivers and streams, particularly in Wicklow and Tyrone. Gold did not require smelting and is a soft metal that is easily hammering and beaten into shape.

One of the significant artifacts from this period are gold Lunulae (s. Lunula). About 60 of these thin gold collars have been found. They are very much an Irish phenomena. The ones that have been found were in areas were they seem to have been placed beyond use, for example in lakes. This may give some explanation for the folklore of gold at the end of the rainbow or Excalibur and the Lady of the Lake surfacing with the famous sword.

Life in the Early Bronze Age

The exploitation of the land by Neolithic and Bronze Age farmers lead to a leaching of minerals of minerals in the soil and the formation of impermeable hard-pan, causing water-logging. The removal of trees also hindered drainage, making the soils wetter. As a result plant remains began to accumulate on the soil surface, facilitating the growth of ling, sedges and Sphagnum. In this way large areas of lowland and hill sides, especially in the west of Ireland, were lost to productive farming. This was aided by a poorer, wetter climate in the Bronze Age. On a positive note, the covering of the landscape by bog has preserved for us the ancient landscape of 6,000 years ago – as well as artifacts, stone walls, and bodies.


At the beginning of the Bronze Age tin may have been had from Wicklow but as the demand increased it would have been imported from Cornwall, possibly exchanged for copper. The composition of bronze was; 90% Copper + 10% Tin
