Home Farm - as seen in the 1989 Emmerdale opening credits.
I've just read on the Web that Home Farm is the only original location in Emmerdale, used right from the start. But I can't see it on my 1972 Emmerdale Farm DVD!
The original locations were Lindley Farm (Emmerdale Farm) and the village of Arncliffe (Beckindale), Mark. The use of Creskeld Hall, originally as the ancestral home of the Verney family, does date back to the '70s, but it was not featured in the first series in 1972.
