The earthwork remains of a post medieval clay pit serving a brickworks can be seen on aerial photographs taken in 1947. These excavations were situated to the north and east of Manor Farm. Circular structures, probably wash mills and a tramway belonging to the brickworks are depicted on the 1866 Ordnance Survey map and are situated within the clay pit. The faint cropmark of one of the three wash mills (6.8m in diameter) can be seen. A cropmark of a similarly shaped feature, though much bigger at 11.8m in diameter is also visible. A further area of extraction was to the north east. This was not depicted by the Ordnance Survey before 1896, by which time the brick works had closed. Part of the site now sits beneath Anthony Way but much of the remaining area is now arable with one part of the clay pit surviving north west of Manor Farm. This site was mapped form aerial photographs as part of the English Heritage: Hoo Peninsula Landscape Project.
