A report in the 1925 Transactions notes, "Recently, when extending in a southerly direction the present Cambridge Road over a portion of ground called the King's Piece in St Mary-at-the-Walls tithe map, a number of shallow pits were found. Roughly a yard across and 18" deep, they showed well in section in the gravel, which here is within 8" of the surface. They were filled with black earth and contained in every case fragments of pottery generally of hard greyish ware; from one however, the whole upper portion of an Iron Age bowl was secured and is now in Colchester Museum.

A note by Hull recordeds the work occurred in 1925, 'to the left of Cambridge Drive off Maldon Road'.<2>
