Most of the earthworks on the Hill of Tara are thought to have been dwelling or feasting places. A long depression runs up the hill from the road towards the Mound of the Hostages. The two sides are high, presumably man-made, earthen banks. This is known as the Banqueting Hall, and for years kids were told it may originally have had wooden walls and a roof. However, this interpretation may have been due to the existence of a seating chart for an ancient King’s banquet, and is likely a good example of people naming a feature to fit in with available relics. A more-likely explanation for this long earthwork is that it may be the remains of one of the five roads that were said to lead to Tara from the five corners of Ireland. It’s easy to see how it could have been a ceremonial entryway, with the high earthen embankments on either side, complete with “windows,” gaps that may have allowed views of significant local landmarks such as the Hill of Skryne on the other side of the Boyne valley, the various tombs of former kings, and possibly a few standing stones.

“The Arena”/Ireland’s Stonehenge
Magnetic gradiometry and other non-invasive survey techniques have recently revealed the remains of a huge structure at Tara. Under the tall grass and several feet of dirt lies a deep ditch dug into the bedrock of the hill. The ditch runs in a circle around the site for about 170 meters (about the length of two football pitches!), encompassing the Mound of the Hostages (and probably the original site of the Lia Fail as well) and the present-day church grounds. This ditch seems to have been surrounded on both sides by an enormous “fence” of huge wooden posts. Circles of wooden posts are not uncommon at this time (1200BCE) — remains of one much-smaller circle have been found and partially reconstructed nearby at Newgrange — but the scale of this one is off the charts. Interestingly, the “banqueting hall” appears to terminate directly at the edge of this ditch, perhaps suggesting the hypothesis that it was a road or ceremonial entryway is more likely.
The exact purpose of this arena (or “woodhenge” as it has been dubbed) is unknown, but as it enclosed the burial chamber known as the Mound of the Hostages and then later the Christian church was built within its boundary, this would suggest it had deep spiritual significance to generations of people. It’s not known what, if anything, was placed on top of the wooden posts, but that hasn’t stopped fanciful artists depicting it as an Irish Stonehenge, with two concentric circles of wooden posts topped with horizontal wooden beams. It’s estimated that at least 500 immense (and old judging by the size of the post-holes) trees would have been required to provide the beams.
One theory holds that the remains of deceased Kings and nobles may have been left to rot inside the arena. Once the flesh was stripped from the bones by decay or birds, the bones would be separated and interred within the mound of the hostages. There is ample evidence of this practice of defleshing a body before burial from elsewhere in the country. Another interpretation is that the aspirant King needed to make a circuit of the arena as part of the spiritual journey toward kingship.
500 years later, around 700BC, an iron age ring fort — simply a large, thick wall of dry-stacked rocks surrounding a building or buildings — was built on the Hill of Tara. This was an advance over the old raths, which were simply a deep ditch with the earth removed and piled up in a bank behind. This represented the labor of many people working together to transport rocks from a larger area and construct the thick protective wall. By this point, the wooden posts surrounding the ceremonial ditch would have rotted away, and evidently the people of that time did not valued the structure enough to replace or maintain it, although the importance of the top of the Hill of Tara appears to have remained undiminished.
This new ring fort was every bit as large as the fenced ditch, but surrounded the top of the hill more exactly (the ditch and ring of posts was on a slight slope). It encircled the rath of the kings and also reclaimed the mound of the hostages. In light of this series of constructions on the Hill which all incorporated the mound of the hostages, it’s obvious how important the inhabitants considered their ancestors, regardless of whatever changes occurred in their mode of worship.
