North Torr 'Castles' - 'Mourne' Mountains - Ireland

North Torr castles - Mourne Mountains County Down N Ireland. 
these rocks look like a man made wall sitting on the top of this mountain - however this is one large piece of rock and part of the mountain - carved and structured into this shape and design by erosion over thousands of years ... its a most unusual sight but one that has to be seen to be believed.
