At the road junction SE274102. It has a tremendous view over the Cawthorne Valley, with the M1 and Barnsley in the background. Good pub nearby, with the same view!
High Hoyland church was once the living of a very colourful and adventurous priest, Joseph Wolff. See http://en.wikipedia.org/wiki/Joseph_Wolff and read Fitzroy Maclean's 'A person from England' [Century Publishing, 1984). Is he celebrated in any way in High Hoyland?
