The end of the Irish Bronze Age merges into the Early Iron Age almost imperceptibly. Not much is known about this period in time and it has been dubbed 'The Irish Dark Age'. It would seem from the evidence so far uncovered that iron use was gradually introduced into Ireland however bronze implements were still very much in use for everyday objects and for ornamentation. Many of the finds dating to the Iron Age include objects decorated in the 'La Téne' style such as the wonderful torc found at Broighter, Co. Derry.
Many finds were made in lakes and around the sites of crannógs (artificial islands). Many horse trappings were discovered dating to this period indicating the importance of horses to Iron Age Man. Many of the 'Historical Romances' transcribed by medieval monks refer to this period in time, the Ulster Cycle and stories of Emain Macha (Navan Fort) are noted in particular. The use of chariots in battle has been attested to in the tales of the ancient warriors.
This is the time of the Celts in Ireland, of the great ring-forts, raids from Ireland to the eastern coast of Britain, capturing goods and people. There has been much speculation about the role of the druids and the aes dána the learned people of the Celts.
