Hey George

I had a look last night and the only reference that I could find was in Anthony Murphy's last book; "Island of the Setting Sun". He reckoned that there was a inter-monument summer solstice alignment from Knowth to Townleyhall (or, as he called it; Site T). Intentional? Maybe, maybe not. But he refers to excavation details in George Eogan's 1986 'Passage Tomb' book - which I don't have. There's a chance (slim, I suppose) that that might have orientation information.

Which county is the tomb in? We've got all of the Survey of megalithic tombs of Ireland volumes, if Townleyhall is one of the counties covered, we'll have a plan diagram for it.

Arch. Inventory Of Co. Louth says "…undifferentiated passage tomb aligned NE–SW with an entrance at the NE end."
It says that the 1960–61 excavation report is in JRSAI 1963, 37–81.
Possible useless info. to you, but there it is.
