This feature is noted in the English Heritage report on the Second World War Stop Line of the Hoo Peninsula, part of the wider Hoo Peninsula study. The report states: [in addition to the six concrete cubes that survive in good condition] "A possible Second World War defence obstruction, on the river wall south east of Hoo St Werburgh, seen on aerial photographs taken in 1942 and 1952. The small structure appears to be an anti-tank cube or pimple associated with an adjacent row of anti-tank cubes (NRHE 1418690) and other components of the stop line. A visit by English Heritage Assessment staff in 2014 confirmed that this structure had been removed although it is possible that sub-surface remains survive. " (7)
