In Northern Ireland, most of the ruins are new...
Not as true as it was a few years ago.
I'm sure I have lots of things I could put on here. In the emantime here's another on an ecclesiastical theme. The old monastic site on Devenish Island, County Fermanagh.
Not as well preserved as Salisbury Cathedral (love to go back there some time - your pictures brought back some good memories...) but pretty elderly. The really old church (foreground) dates from about 850, or thereabouts. The round tower was built after the threat from our Danish cousins (Vikings) had gone, around 1250.
I know, I know... I should have stood a few feet to the left and not had the gravestone directly in front of the tower.
