The earliest mention of Gloster Hill is in a 12th century charter by which Roger fitz Richard (died 1178) gave certain saltworks to the abbot and convent of Newminster. The place or field where the water, which runs below Gloster, falls into the River Coquet, is now called the Goatses and the water retains its name of the Gilden burn. A portion of this field has never been ploughed and the site of the salt pan can be discerned when the sun burns the pasture in summer; the identification has also been confirmed by digging.

[Area centred NU 25660474]. The field known as Goatses (as delineated on 6 inch) consists of low-lying permanent pasture.
At the time of investigation there was no trace to be seen of the salt pans mentioned in T1.
The stream running down the east side of the field is now called Guilders Burn (Gilden Burn in T1). (2)

No better siting obtained under summer conditions. (3)

A possible sleeching (waste) mound was noted at Gloster Hill. It is a large flat mound, with some gorse growing on it, probably tipped from the south west. (4)
