Suffolk RCZAS - Targeted Inter-tidal Survey Report
Following a rapid walkover survey of the Suffolk coast and inter-tidal estuaries, nine of the sites recorded were identified as potentially archaeologically significant (Everett et al 2003). These were earmarked as requiring further work, not only to better understand them as individual sites, but also to be able to provide a strong curatorial response to coastal planning as it impacts on the historic environment. Radiocarbon dating of a fish trap in Holbrook Bay on the River Stour returned a date of cal AD 680– 850 (at 95% probability from the Bayesian model) for its main structure, confirming the Saxon date that was supposed from its form and parallels. Five other post-built structures in Holbrook Bay were radiocarbon dated to the post-medieval period and further samples submitted from these features may be able to date them more closely. A series of posts, laid timbers and possible wattle fragments at Barber’s Point on the River Alde were planned and dated. Whilst the plans hinted at the possibility of trackways or a fish trap, no function for the structure was obvious from the plans alone. Radiocarbon samples dated the feature to cal AD 650–780 (at 95% probability from the Bayesian model), a date which ties in with known Saxon activity on the banks of the river within 50m of the waterlogged wood.
