Evaluation by K Krawiec for ASE confirmed the presence of the former castle moat, although the edge of the moat was not observed. A borehole survey confirmed that 19th century backfill made up a large proportion of the material infilling the moat, although the primary fills included an in-situ organic deposit. The lower deposits did not yield reliable material for dating, but a layer of leaf litter returned a date of 1670 cal AD to post-1950 cal AD (280-10 cal BP). The remains of a sandstone foundation course for a brick-built house that appears on the OS 1st edition map as Moat House were also recorded.
