 The trial pit in Sir Thomas Stepney's Study however told a very different story from the re-opened trial pits in the former Great Hall and the south-western range.This trial pit revealed that the under-floor material was a single fill deposit characterised by demolition material of small stones, mortar and soil.An interesting feature exposed in this preliminary trial pit was a narrow north to south aligned stone built cross wall, which was partly supporting the present floor joists.
