Initial remote sensing survey at Tlachtga, Co. Meath in 2011–12 highlighted the presence of multiple, partially overlapping phases of enclosure at the site. Three subsequent seasons of excavation provided critical interpretive evidence, with over 15,000 fragments of animal bone, human remains, charred plant material, evidence of metalworking, and a hoard of Anglo-Saxon silver coins dating to the late 10th century AD. The main activity at the site spans four broad periods and two main phases of monumental construction: a late Bronze Age to early Iron Age ‘Hillfort Phase’ (1100–400 BC) and a late Iron Age to early medieval (AD 400–600) ringfort phase associated with a smaller foundation enclosure – the ‘Southern Enclosure’. This ringfort phase was remodeled later in the early medieval period (9th–10th century AD) and augmented by a phase of mound construction in the mid-10th century AD. This is contemporary with the deposition of the coin hoard east of the main complex in an apparent craft-working area. The final phase of the central mound indicates the construction of a timber stockade, most likely in the 12th century, again with significant craft activity. This volume represents the excavation of at least four loci within the broader monumental landscape of Tlachtga, charting its progression from Bronze Age hillfort to pre-Anglo Norman power display mound. The excavations at the Hill of Ward and this publication were made possible through funding by the National Monuments Service via the Royal Irish Academy archaeological research excavation grants, and by Meath County Council, with additional support by the Office of Public Works and the Heritage Council.

Tlachtga is one of very few quadrivallate ringforts in Ireland and a site that has long been regarded as of potential 'Royal' status. It is a site with significant associated folklore and historical narrative associated with it. In the 12th century, Tlachtga was the scene of negotiations between Hugh de Lacy and Tighernan Ui Ruairc, king of Breiffne, at which Ui Ruairc was said to have been slain by treachery and his head sent to Henry II in London. Initial remote sensing survey in 2011-12 using both lidar and multi-method geophysical survey highlighted the presence of multiple, partially overlapping phases of enclosure at the site. Three subsequent seasons of excavation yielded over 15,000 fragments of animal bone, human remains, charred material, evidence of metalworking, and a hoard of 23 Anglo-Saxon silver pennies. The earliest material culture comprises lithics and two small sherds of middle Neolithic pottery. The main activity at the site seems to span two periods: a late Bronze Age to early Iron Age (1100-400 BC) trivallate hilltop enclosure and a late Iron Age to early medieval (AD 400-1000) enclosure phase. This latter in particular sees a great deal of development from a 40 m univallate enclosure to a 150 m quadrivallate enclosure, and finally a phase of mound building where the central space is converted to a 'rath mound' probably in the mid-10th century. This is contemporary with the deposition of the coin hoard just east of the main complex in an apparent craft-working area. The final phase examined seems to indicate a timber stockade constructed on the central mound, most likely in the 12th century.

The early medieval manuscripts of Ireland and Britain contain tantalizing clues about the cosmology, religion and mythology of native Celtic cultures, despite censorship and revision by Christian redactors. Focusing on the latest research and translations, the author provides fresh insight into the beliefs and practices of the Iron Age inhabitants of Ireland, Britain and Gaul. Chapters cover creation and cosmogony, the deities of the Gaels, feminine power in narrative sources, druidic belief, priestesses and magical rites.

'An excellent and comprehensive exploration of this fascinating subject.' - Philip Carr-Gomm, author Druid Mysteries ' Samhain was the entry point into winter, a time of hardship, cold and hunger ... It was also a time of introspection, of communing with the dead and the otherworld – themes that have somehow survived, albeit distorted, into the modern era.' The modern celebration of Halloween is derived from the ancient festival of the dead known in Ireland as Samhain. It is from Ireland that we have inherited most of our Halloween traditions, mainly through the diaspora. Delving into the ancient past, this book uncovers the history of this festival in Britain, Ireland and Brittany, including the forgotten goddess Tlachtga and the sacred temple of the Druids in Co. Meath, where the first Halloween fires were lit.

This book provides a comprehensive overview of pedology in Ireland. It describes the main soil types of the country, their functions, ecological use, and the conditions to which they were subjected associated with management over time. In addition, it presents a complete set of data, pictures and maps, including benchmark profiles. Factors involved in soil formation are also discussed, making use of new, unpublished data and elaborations. The book was produced with the support and sponsorship of Teagasc, The Agriculture and Food Development Authority, Ireland and the Irish Environmental Protection Agency.
