Iv'e been to the tallest stones in England, Wales, Scotland and the Republic of Ireland but not Northern Ireland which one is it ?
Also which is the tallest standing stone in the World ?
Hmmm Norn Iron's tallest stone.... They dont get very tall as far as I know (which isn't a whole lot!), maybe this one is a contender: http://www.themodernantiquarian.com/post/3791
I think the egyptian obelisks must be the tallest in the world, which one I've no idea though!
