Ten weeks ago, we began an incredible community excavation on Mersea Island to record the Tudor Blockhouse at Cudmore Grove Country Park before coastal erosion claimed more of its story.
What followed was something truly special. We were overwhelmed by the support of local volunteers, veterans through Operation Nightingale and the wider community. Together, we uncovered a wealth of finds, shared knowledge, made lasting connections and helped preserve an important piece of local heritage.
The excavation may be over, but the work continues. Many volunteers are still joining us each week at Roman Circus House to help process the substantial quantity of artefacts uncovered during the project.
This fantastic project, organised by Place Services at Essex County Council, brought together members of the local community and veterans through Operation Nightingale. It was funded by the Department for Environment, Food and Rural Affairs and supported by Historic England through the Countryside Stewardship Heritage Service.
To everyone who took part, visited, shared their expertise or supported us along the way: thank you. Your contribution has helped preserve an important part of Mersea's history for future generations.
There is much more to come, and we look forward to sharing the story of the Tudor Blockhouse as the post-excavation work progresses.
