54.—Ground Plan and Section of the Subterranean Chamber at Carrighhill.details

I think the place mentioned is probably Carrick, and in particular either the neolithic Carrick East Burial Chamber or Carrigadoon Hill, but I am not certain. At any rate the text makes clear that it is in Ireland, but says nothing more. The cited archaeological report mentions Fermoy in its title (the contents are online).
