NHER Number:23205
Type of record:Monument
Name:Iron Age and Roman pot boiler sites in two fields southwest of Tower Mill


Two pot boiler sites were recorded during fieldwalking. A fragment of Iron Age pottery was found on one site, and Roman pottery was recovered from the other site which has been interpreted as the location of some kind of industrial activity. Fieldwalking also recovered worked flints dating from the Beaker period and fragments of medieval pottery.

Sherd is Iron Age - F. Healy (NAU).

Context 3 at 6609 1431. MDT 8.

Further work at Contexts 2 (MDT 7) and 3 (MDT 8).
Accuracy of original site location plots checked; samples of subsoil taken by auger for analysis - shown to be watelogged silt, possibly with botanical preservation. Sites not well preserved (not peat covered) Not recommended for preservation to Historic Buildings and Monuments Commision.

MDT 7.
Iron Age activity might be anticipated on the basis of a single sherd of pottery found on a pot boiler site at the peat edge; more associated material is required from the site to confirm the dating, but with a Roman pot-boiler spread a short distance away (MDT 8) and the absence of any other Iron Age sherds in the vicinity, the assessment is reasonable.

MDT 8.
This pot-boiler spread produced enough Roman pottery mixed with the calcined flint and ash to leave no doubt to its date, even if its function is unclear. It was positioned on the edge of a small dry valley running towards Blackborough End that was filling with peat in the medieval period and may have become waterlogged even earlier, so industrial activity of some sort must be suspected. The associated Roman settlement seems to have been beneath the modern settlement of Blackborough End.
