The results of the Dunwich 2008 project are important for six main reasons:
- These are the first formally identified mediaeval structures identified by geophysical survey in UK coastal waters.
- The project has demonstrated the preservation of larger medieval stone structures in the coastal zone, and their close proximity to their original locations after up to 500 years of submergence.
- The survey confirms the existence of church ruins from the former medieval town of Dunwich, and pinpoints their precise position. They suggest that other church structures are likely to exist beneath the sand banks.
- The survey has demonstrated the value of integrated cartographic and geophysical survey as a means for locating and identifying maritime heritage from former medieval settlements from poor visibility, medium energy coastal environments. This opens up the challenge of how to legislate for the protection of non-wreck heritage in the coastal zone.
- Finally, the outputs from the project, have been used to develop new learning materials in support of the Dunwich Museum trust and to promote a wider understanding of the story and investigation of Dunwich.
- The visibility was still a constraint, and the survey highlighted limitations of geophysical survey tools as deployed in the project. The next phase will be to return with higher resolution acoustic imaging equipment to map the church sites, and to conduct sub-bottom profiling in search of the remaining lost churches of Dunwich.
