Millmount is a medieval motte-and-bailey fort, fortified by the de Lacy family in the 1170s and refortified in 1808. Its origins remain disputed: official heritage information says it may conceal a large passage tomb, while archaeological data questioning that possibility have also been presented. Cillín Barrain Carberry recorded local folklore linking Millmount with Brú na Bóinne and describing subterranean passages said to have been blocked by later fortification. The video argues that the equinox sun sets over the Hill of Slane and the winter-solstice sun over Tara from Millmount, presenting those alignments as evidence of an ancient origin. They do not establish that a Neolithic passage tomb lies beneath the fort. 🏛️🌅 09:08-13:18
