<div class="mw-heading mw-heading2"><h2 id="Description">Description</h2></div>
<p>The large mound has been estimated to date from c. 3200 BC. The mound is about 12 metres (40 ft) high and 67 metres (220 ft) in diameter,<sup id="cite_ref-Harbison_3-0" class="reference"><a href="#cite_note-Harbison-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup> covering roughly a hectare. It contains two passages placed along an east–west line and is encircled by 127 <a href="Glossary_of_archaeology" title="Glossary of archaeology">kerbstones</a>, of which three are missing, and four badly damaged. The passages are independent of each other, leading to separate burial chambers. The eastern passage arrives at a <a href="Cruciform" title="Cruciform">cruciform</a> chamber, not unlike that found at <a href="Newgrange" title="Newgrange">Newgrange</a>,<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> which contains three recesses and basin stones into which the <a href="Cremated" class="mw-redirect" title="Cremated">cremated</a> remains of the dead were placed. The right-hand recess is larger and more elaborately decorated with <a href="Megalithic_art" title="Megalithic art">megalithic art</a> than the others, which is typical for Irish passage graves of this type. The western passage ends in an undifferentiated chamber, which is separated from the passage by a <a href="Threshold_stone" title="Threshold stone">sill stone</a>. The chamber seems to have also contained a basin stone which was later removed and is now located about two-thirds down the passageway.
</p>
<div class="mw-heading mw-heading3"><h3 id="Megalithic_art">Megalithic art</h3></div>
<p>Knowth contains more than a third of the total number of examples of megalithic art in all of Western Europe; over 200 decorated stones were found during excavations. Much of the artwork is of an abstract style and is found on the kerbstones, particularly approaching the entrances to the passages.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup>
</p><p>Many of the motifs are typical: <a href="Spirals" class="mw-redirect" title="Spirals">spirals</a>, <a href="Lozenge_(shape)" title="Lozenge (shape)">lozenges</a> and <a href="Serpentiform" class="mw-redirect" title="Serpentiform">serpentiform</a>. However, the megalithic art at Knowth contains a wide variety of images, such as crescent shapes, and the oldest known <a href="Selenography#Lunar_cartography_and_toponymy" title="Selenography">illustration of the moon</a> in history.<sup id="cite_ref-Stooke_6-0" class="reference"><a href="#cite_note-Stooke-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> Much of this artwork was carved on the backs of the stones; a type of megalithic art known as hidden art. This suggests all manner of theories as regards the function of megalithic art within the Neolithic community who built the monuments in the Boyne valley. It is possible that they intended the art to be hidden. It is also possible that they simply recycled the stones and reused the other side.
</p>
<div class="mw-heading mw-heading3"><h3 id="Astronomical_alignments">Astronomical alignments</h3></div>
<p>The east–west orientation of the passages at Knowth suggests astronomical alignment with the <a href="Equinox" title="Equinox">equinoxes</a>. The alignment at Knowth does not occur today. This is due to a number of factors. First of all, the passages were discovered by later settlers and were, to some extent, destroyed or incorporated into souterrains. In this way the original entrances to the passages were distorted or destroyed, making it difficult to establish if an alignment ever existed. Further, the recent excavations (1962 onwards) under George Eogan resulted in the erection of a concrete slab wall inside the mound's west entrance, restricting any investigation into the possible alignments. It seems likely that the passages were intended to align. Also, the alignments of ancient monuments can change due to <a href="Milankovitch_cycles" title="Milankovitch cycles">Milankovitch cycles</a>. The most extensive research on alignments and astronomy at Knowth was carried out by American-Irish researcher Martin Brennan.<sup id="cite_ref-7" class="reference"><a href="#cite_note-7"><span class="cite-bracket">[</span>7<span class="cite-bracket">]</span></a></sup>
</p>
<div class="mw-heading mw-heading2"><h2 id="History">History</h2></div>
<p>There is some evidence for late Neolithic and <a href="Prehistoric_Ireland#Copper_and_Bronze_Ages_(2500–500_BC)" title="Prehistoric Ireland">Bronze Age</a> activity on the site. Most of this stems from the existence of a <a href="Grooved_ware" title="Grooved ware">grooved ware</a> timber circle located near the entrance to the eastern passage. Archeological evidence suggests that this was used as a ritual or sacred area after the great mound at Knowth had already fallen into disuse. Evidence for ritual consists of a large number of <a href="Votive_deposit" class="mw-redirect" title="Votive deposit">votive offerings</a> found in and around the immediate areas of the timbers that formed the circle.
4r[2
The hill at Knowth fell into disrepair, and the mound or cairn slipped, causing the entrances to both passages to be covered. The site remained practically unused for a period of two thousand years. The site was briefly used as a burial site; some 35 <a href="Cist" title="Cist">cist</a> graves were found on the site during excavations.<sup id="cite_ref-8" class="reference"><a href="#cite_note-8"><span class="cite-bracket">[</span>8<span class="cite-bracket">]</span></a></sup>
</p><p>In the late <a href="Prehistoric_Ireland#Iron_Age_(500_BC–AD_400)" title="Prehistoric Ireland">Iron Age</a> and early Christian period, it became a <a href="Hill_fort" class="mw-redirect" title="Hill fort">hill fort</a> with encircling ditches and <a href="Souterrain" title="Souterrain">souterrains</a> added. Knowth became a habitational site for the first time. Two ditches were dug, one at the base of the mound behind the kerbstones, and the other at the top. At this stage, the entrances to both passages seem to have been discovered. Evidence includes early Christian graffiti on the stones in the eastern chamber, and four names were carved in <a href="Ogham" title="Ogham">ogham</a>. It seems it was at this stage that the basin stone from the western chamber was moved in an attempt to remove it and was abandoned in the passage because it got stuck. Knowth became a significant political site and the capital of the <a href="Kings_of_Brega" title="Kings of Brega">Kingdom of Northern Brega</a>.<sup id="cite_ref-9" class="reference"><a href="#cite_note-9"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup>
</p><p>Knowth was called <i>Cnogba</i> in <a href="Old_Irish" title="Old Irish">Old Irish</a>, whose meaning is unclear.

</p><p>After a brief military interlude following the <a href="Anglo-Norman_invasion_of_Ireland" title="Anglo-Norman invasion of Ireland">Norman invasion of Ireland</a>, when the Normans used Knowth as a motte in the 12th century,<sup id="cite_ref-14" class="reference"><a href="#cite_note-14"><span class="cite-bracket">[</span>14<span class="cite-bracket">]</span></a></sup> the site came into the possession of the <a href="Cistercians" title="Cistercians">Cistercian</a> monks of <a href="Mellifont_Abbey" title="Mellifont Abbey">Mellifont Abbey</a>. It seems that the mound was then again used as a grange or farm. Stone walls were built over the mound, and stone buildings within the walls. After the dissolution of the monasteries, the site was used mainly for agriculture until most of the site was taken over by the state in 1939.
</p>
<div class="mw-heading mw-heading2"><h2 id="Archaeological_investigation_and_restoration">Archaeological investigation and restoration</h2></div>
<p>A brief excavation of the site was carried out in 1941 by Macallister. However, the first thorough archaeological investigation and excavations of Knowth began in 1962 and were led by <a href="George_Eogan" title="George Eogan">George Eogan</a> of <a href="University_College_Dublin" title="University College Dublin">University College Dublin</a>. When his excavations began, very little was known about the full extent of the site. The entrances to the western and eastern passages were discovered in 1967 and 1968 respectively, and, slowly, the layers of activity at the site of Knowth were uncovered.<sup id="cite_ref-knowth_excavations_15-0" class="reference"><a href="#cite_note-knowth_excavations-15"><span class="cite-bracket">[</span>15<span class="cite-bracket">]</span></a></sup> The excavation has produced numerous books and reports on the findings. Following the excavation, <a href="Conservation_and_restoration_of_archaeological_sites" title="Conservation and restoration of archaeological sites">conservation, restoration and reconstruction</a> works took place.
</p><p>A layer of white quartz stones was found at the entrances to the great mound. The same was found at the entrance to Newgrange, and the archaeologists there concluded that it had made up a white <a href="Fa%C3%A7ade" title="Façade">façade</a> or <a href="Revetment" title="Revetment">revetment</a> on the front of the monument that had fallen. This white quartz front was reconstructed at Newgrange.<sup id="cite_ref-16" class="reference"><a href="#cite_note-16"><span class="cite-bracket">[</span>16<span class="cite-bracket">]</span></a></sup> However, George Eogan did not believe Neolithic people could have built such a revetment without it collapsing. He suggested that most or all of the white quartz had been spread on the ground, and so it was left on the ground at Knowth. While some archaeologists have supported this decision, other archaeologists argue that both Knowth and Newgrange had white quartz façades, such as Robert Hensey and Elizabeth Shee Twohig in their paper "Facing the cairn at Newgrange" (2017).<sup id="cite_ref-Hensey_Twohig_17-0" class="reference"><a href="#cite_note-Hensey_Twohig-17"><span class="cite-bracket">[</span>17<span class="cite-bracket">]</span></a></sup> They note that the quartz layers at both sites were thickest nearest the kerbstones, suggesting it had slid down the mound rather than being laid flat. They also contend that if the builders quarried and brought the quartz a long distance, they likely would have used it to "maximum effect" as a striking façade, rather than laying it on the ground where it could not be seen as well.<sup id="cite_ref-Hensey_Twohig_17-1" class="reference"><a href="#cite_note-Hensey_Twohig-17"><span class="cite-bracket">[</span>17<span class="cite-bracket">]</span></a></sup> Along with archaeologist Carleton Jones,<sup id="cite_ref-18" class="reference"><a href="#cite_note-18"><span class="cite-bracket">[</span>18<span class="cite-bracket">]</span></a></sup> Hensey and Twohig note that passage tombs in <a href="Brittany" title="Brittany">Brittany</a> have similar near-vertical <a href="Dry_stone" title="Dry stone">dry stone</a> fronts, such as <a href="Gavrinis" title="Gavrinis">Gavrinis</a> and <a href="Barnenez" title="Barnenez">Barnenez</a>.<sup id="cite_ref-Hensey_Twohig_17-2" class="reference"><a href="#cite_note-Hensey_Twohig-17"><span class="cite-bracket">[</span>17<span class="cite-bracket">]</span></a></sup>
