Actually, yeah - that is pretty spot on. The monuments can be pretty bloody impossible to find sometimes! We've often been in search of a stone or well, marked nicely in script (the text taking up to about half a mile by the scale of the map) and pondered whether it's this dot or that blemish it's referring to!
Sometimes it's the fun of the search - other times it's a pain in the arse! ;)
Will say that for the French ones as well - the monuments are marked pretty damn obviously!
I'd imagine that, by the time I actually get my arse over to Ireland, the new maps will be well in force, so I'll not know any different! ;)
