In April 1953 two trenches were cut to a depth of 1.22m by a mechanical excavator at right angles to the River Stour on a site lying SW of the Tannery and NE of St Mildred's School. The site code was CXXIIIK. It was hoped to find a NS Roman street, but waterlogged and muddy conditions impeded the excavations and the results were inconclusive.
Trench II was waterlogged and produced nothing of note.
The lowest level reached in Trench I was a layer of gravel, thought to be natural. Overlying this was a thin layer of occupation material and bones, possibly part of a Roman Street.
Above the gravel was a deposit of black pebbly mud 1.37m thick. This was probably a result of flooding.
