A team of researchers has begun searching for "the lost landscapes" of the Irish Sea that were flooded as the sea level rose in ancient times. The team, from the Irish Marine Institute and IT Sligo, has joined with a University of Bradford "Lost Frontiers" programme to explore the extensive submerged landscapes between Ireland and Britain.
A new study in the journal Nature suggests that the Neolithic population of ancient Britain was almost completely replaced by newcomers, the Beaker people, by about 2500BC. The huge study involved the extraction of DNA from 400 ancient Europeans, including samples from Neolithic, Copper Age and Bronze Age peoples, 226 of them from the Beaker period.
As we say goodbye to 2017 on this, New Year's Eve, I've decided to take a trawl through my photographs of ancient sites from the past 12 months and pick out my favourites for you to enjoy. I hope you like them as much as I loved taking them. Happy New Year!
I feel honoured and privileged to be able to stand in the doorway of Síd in Broga on the shortest mornings of the year and to be present at this special moment in the same place as those distant ancestors once stood.
As we approach the winter solstice, and the celebrated illumination of the 5,200-year-old chamber of Newgrange by the rising sun on the shortest days, I've decided to pick out my favourite images of the famous megalithic monument from the past 12 months. Some of these choices were easy, as in a few cases I think the images are very dramatic and unique. In other cases, I had a harder choice. There are a lot of very good images that didn't make the final gallery.
In 2016, in the lead-up to the winter solstice at Newgrange, I released a series of images called The 12 Days of Solstice. Each day I released a new image until the day of the solstice itself. Here is that series of images, in one gallery, for you to enjoy.
There are many archaeological monuments and features in the Brú na Bóinne complex. Some of these are very obvious in the landscape – there are passage-tombs, mounds, enclosures, standing stones and cursus monuments. However, others that are less obvious provide archaeologists with many questions.
Sometimes, the most interesting coincidences occur. Today, I was lucky to have been able to spend a few hours at Loughcrew in glorious winter weather. There was a mix of mist and fog, sunshine and cloud and the atmospheric conditions made for some wonderful photography.
A fascinating discovery in the darkness of a cave in County Clare has forced archaeologists to rewrite the history of Ireland. A bear bone found in the cave pushes back the date of human presence in Ireland by 2,500 years - to 12,500 years ago.
It's competition time. To celebrate the dual launch of my new book Mythical Ireland: New light on the Ancient Past, and the new-look www.mythicalireland.com website, I am giving one lucky follower the chance to win a copy of the new book.
It's not exactly megalithic, although it was built with lots of stone. It's not exactly Neolithic, belonging more to the Medieval period. But the Old Abbey, tucked away in the centre of Drogheda not far from the main street, is a real historical and archaeological treasure. Its proper title is the Abbey and Hospital of St. Mary d'Urso.
What a momentous day it's been today. I didn't plan it this way, I can assure you, but the first two copies of my new book, Mythical Ireland: New Light on the Ancient Past arrived at my publisher The Liffey Press. And the new Mythical Ireland website went live too. On the same day. And it's Samhain!
This large henge (embanked enclosure) located beside the River Boyne at Brugh na Bóinne, known on archaeological maps simply as Site P, has been identified tentatively by archaeologist Geraldine Stout as the site referred to in ancient lore as Caisel nOengussa, the Cashel of Oengus.
37 years ago, in 1980, Martin Brennan, Jack Roberts and their team of researchers made several significant discoveries relating to the astronomical alignment of several ancient chambered cairns (passage-tombs) in the Boyne Valley region. One such discovery, made in early August of that year, was the apparent alignment of the passage of Cairn S at Carnbane East, Loughcrew. Sitting in the chamber of the (now roofless) cairn, Brennan and his team saw that the Lughnasadh cross-quarter sunset was visible through the passage.
Back in February of this year, at Imbolc, myself, Ken Williams and Lar Dooley witnessed the sunrise shining into the ancient passageway of Cairn U at Carnbane East, Loughcrew. That day, I noticed that when I was crouched in the chamber of Cairn U, the Hill of Tara was visible through the entrance of the passage. Based on that observation, I figured that a viewer on the Hill of Tara might see the sun setting over the hills of Loughcrew at Bealtaine (May) and Lughnasadh (August).
