I wasn’t sure whether to add the great Eire to TNA, for three reasons: (i) I’ve never sailed across the waters to explore the wealth of sites there; and (ii) as a result, I know next to nowt about the places there! The third and biggest reason has got to be the Megalithomania site, which covers masses of archaeological sites over there — better than probably any other site on the web, as a click here will show!
