4Westropp, T.J. "Prehistoric Stone Forts of Central Clare. Moghane and Langough, near Dromoland." The Journal of the Royal Society of Antiquaries of Ireland Fifth 3.3 (1893): 284-85.
"Not only is Moghane, even in its overthrow, a most interesting example of our prehistoric forts, but it is probably one of the largest (whether of earth or stone) in Ireland. It could contain Dun Aonghus and Dun Conor, Emania, or the two largest forts of Tara; while, to give a definite notion of its great size, it is three times the length and four time the greatest width of St. Paul’s Cathedral, or three times the size of the Acropolis of Athens."
