ティペラリー州には、Fulacht na Mór Ríoghna(「モリガンの調理場」)と呼ばれる焼失墳丘遺跡がある。フルアチャイ遺跡は、野山にあり、通常、フィアンナなどの部外者や鹿の狩猟に関連した遺跡である。その名は英雄クー・フーリンを破滅に導く犬の肉を調理する神話の3人の老婆と関係があるのかもしれない。Dá Chích na Morrígna(「モリガンの二つの胸」)はミース州のブルー・ナ・ボインの近くにある二つの丘で、ケリー州のDá Chích Anann(アヌの胸」)という丘を持つアヌと同様に、監督する女神としての役割を示唆しているとされる。同じような丘を持つ女神として、リムリック州のアインとグリアンが知られているが、彼らは指導的な役割に加え、太陽的な属性も持っている。
==Arthurian legendアーサー王伝説 =={{further|Morgan le Fay}}
There have been attempts by some modern researchers and authors of fiction to link the Morrígan with the character of Morgan, the latter often being depicted in the legend as a [[fairy]] or otherwise supernatural sister of [[King Arthur]]. Morgan first appears in literature in [[Geoffrey of Monmouth|Geoffrey of Monmouth's]] 12th-century ''[[Vita Merlini]]'' as a goddess-like figure in no blood relation to Arthur, whom she takes to her Otherworld style land of [[Avalon]] following his mortal wound in a battle. In some Arthurian texts, such as ''[[Sir Gawain and the Green Knight]]'', Morgan is portrayed as a hag whose actions set into motion a bloody trail of events that lead the hero into numerous instances of danger. Morgan is also depicted as a seductress, much like the older legends of the Morrígan, and has numerous lovers whom she might be even abducting for this purpose (as in some stories of [[Lancelot]] and [[Ogier the Dane]], among others). The character is frequently depicted as wielding power over others to achieve her own purposes, allowing those actions to play out over time, to the benefit or detriment of other characters.<ref>{{Cite book|title = Morgan le Fay in Sir Gawain and the Green Knight|url = http://www.shmoop.com/sir-gawain-green-knight/morgan-le-fay.html}}</ref>
