Tump is a western English dialect word, first recorded at the end of the 16th c.AD, meaning a mound. George Whitefield (pronounced Whitfield) was said to be the greatest orator of his age. A Calvinist evangelist, he preached to thousands in the open air across England and in North America. He is said to have addressed a large crowd from the top of this long barrow in 1743AD. Hence the name, Whitfield’s Tump.
