Winter Solstice - Tuesday 21 December 2021 - LIVE

The Winter Solstice is an astronomical phenomenon that marks the shortest day and the longest night of the year. In the Northern Hemisphere, the Winter Solstice occurs on 21st or 22nd of December, when the sun shines directly over the tropic of Capricorn. At sunrise on the shortest day of the year, for 17 minutes, direct sunlight can enter the Newgrange monument, not through the doorway, but through the specially contrived small opening above the entrance known as the ‘roof box’, to illuminate the Chamber.
In line with the revised Government Guidelines, Brú na Bóinne Visitor Centre and the site at the Newgrange Monument - though not the passage tomb itself - are currently open to visitors. We will once again live-stream the Winter Solstice on this page at 08:45 UTC on the 20th, 21st and 22nd of December, so make sure to join us to view the spectacular phenomenon and learn some fascinating facts.
Is feiniméan réalteolaíoch é Grianstad an Gheimhridh a cheiliúrann an lá is giorra agus an oíche is faide sa bhliain. Sa Leathsféar Thuaidh, tarlaíonn Grianstad an Gheimhridh ar an 21 nó an 22 Nollaig, nuair a scalann an ghrian go díreach os cionn Thrópaic an Ghabhair. Ar feadh 17 nóiméad, ag éirí na gréine ar an lá is giorra sa bhliain, is féidir le solas na gréine scaladh díreach isteach sa séadchomhartha ag Sí an Bhrú, ní tríd an doras, ach tríd an oscailt bheag a cruthaíodh d’aon ghnó os cionn an bhealaigh isteach, ar a dtugtar ‘bosca an dín’, ag leathadh an tsolais ar fud an tSeomra.
De réir Threoirlínte athbhreithnithe an Rialtais, tá Ionad Cuairteoirí Bhrú na Bóinne agus an láithreán ag Séadchomhartha Shí an Bhrú ar oscailt do chuairteoirí faoi láthair - ach níl an tuama pasáiste féin ar oscailt. Déanfaimid beoshruthú arís ar Ghrianstad an Gheimhridh ar an leathanach seo ag 08:45 AUL ar an 20, 21 agus 22 Nollaig, mar sin déan cinnte a bheith linn chun an feiniméan iontach seo a fheiceáil agus roinnt fíricí spéisiúla a fhoghlaim.

Very delighted to see the 1979 solstice footage with professor O'Kelly (toward the end).
