The earthwork of an oval mound circa 13m by 9m is visible on aerial photographs taken in 1947. This is one of two probable post medieval livestock refuge mounds within a field towards the eastern end of Cooling Marshes. This mound had been levelled by 2007. Refuge mounds provided an area of high ground for livestock to occupy in the event of a flood and numerous refuge mounds were built on the marshes of the Hoo Peninsula. This site was mapped from aerial photographs as part of the English Heritage: Hoo Peninsula Landscape Project.
