Timber-framed wheelpit and tailrace
View of the wheel pit before excavation. The clay packing around the outside has been removed; pressure on the pit had caused it to collapse.
The wheelpit and tailrace probably date to the sixteenth century, although they may be earlier. Finds excavated so far suggest that it went out of use in the seventeenth century.
These brick structures overlie another series of substantial timbers which form part of the sixteenth century forge.
Work will continue on the site until Easter.
