I was looking at a map on Hampstead Heath the other day and noticed Preachers hill marked on it. Apparently a grove stood near Hampstead with a large green and an old village tree. In 1739 (Thursday May 17) George Whitfield preached there. Hence Preacher's Hill. Preachers Hill is situated off East Heath Road, opposite the top of Pryors Field.
'Preached, after several invitations thither, at Hampstead Heath, about five miles from London. The audience was of the politer sort, and I preached very near the horse course, which gave me occasion to speak home to the souls concerning our spiritual race. Most were attentive, but some mocked. Thus the Word of God is either a savour of life unto life, or of death unto death. God's Spirit bloweth when, and where it listeth.'
His visit is said to have led to the founding of a Congregationalist church.
