This post summarises it (
Fasgadh):
Tump (English spelling) is a rare word away from Wales and the border areas. It exists in both languages and means a pile or small hill. While it is an everyday word for us, I would be surprised to see it over the other side of England - but its possible.
Not sure if the feature is officially called Beeston Hill as in some of the other pictures for the square, Beeston Bump seems to be the preffered name locally I think.
