Evaluation by S Wallis of TVAS revealed over twenty deep rectangular tanks. Historic maps illustrate that the site was formerly occupied by a 19th century tannery, and the tanks were almost certainly once part of this complex. Many were timber lined, and all appeared to have been deliberately backfilled prior to the demolition of the tannery buildings in the early 20th century. No artefacts or deposits pre-dating the 19th century were identified.
