2008 Irish language documentary extract covering a rather interesting confrontation between a handful of prominent Irish nationalists-Arthur Griffith,Maud Goone and a particularly vile cult of (((British))) aristocrats over domination of the spiritually important site of Tara-ironically rather similar to St Patricks initial battle with the druids in the reign of Lóegaire mac Néill.
