Since this celebration is for TWO Millennia, why not consider
- the best blg. of the First Mill.,
- the best blg. of the Second Mill.,
and if anyone is up for it, the best outright winner!
For the First Mil., - one of the great cashels or stone forts,
For the Second, surely a Romanesque or Gothic ensemble, as only there is embodied a coherent and authentic sculptural and/or painting programme that all great architecture encompasses (there is no Baroque in Ireland).
