Dunluce Castle in my own County Antrim.
Used by Led Zeppelin in their album artwork for Houses of the Holy
I won't bore you with all of the details as I have written previously about Dunluce Castle on County Antrim's Causeway Coast here: http://panoramicireland.com/photo-tours-blog/cow-in-front-of-dunluce-castle-causeway-coast-antrim-northern-ireland
Dunluce and the Causeway Coast is a place that I lead many photography workshops and tours in.
