The Cotswold Archaeology team uncovered the timber structure, which dates to the Middle Bronze Age, approximately 1500 BC to 1100 BC. Finds made from organic materials such as wood rarely survive for millennia, making this discovery particularly significant. The Bronze Age well owes its exceptional state of preservation to the waterlogged conditions of the surrounding soil, which effectively sealed the timber from oxygen and slowed decomposition.

Uncovering Ancient Engineering
As archaeologists from Cotswold Archaeology carefully exposed the site, a complex picture of deliberate engineering emerged. The structure features an upper platform constructed from fitted planks and rounded wooden beams. From this platform, a timber ladder descends into a lower chamber where water would have been collected and stored.
According to a report by BBC News, the excavation also revealed wattle walls, a 'corduroy' trackway made of aligned planks, and a wooden trough. Much of the wood appears to have been repurposed from other timber structures, showing evidence of splitting and tool markings. This indicates a highly resourceful approach to construction by the Bronze Age inhabitants.
Paolo Guarino, a post-excavation manager with Cotswold Archaeology, highlighted the rarity of the find.
"It's not that often that we find wood," he explained. "Water-logged conditions are some of the best for the preservation of organic matter like timber" recorded the BBC News.

Climate Change and Prehistoric Water Strategies
One of the most intriguing aspects of the Bronze Age well is its location. Today, the surrounding region is rich in natural water sources, including streams and rivers. This raises a key question: why would prehistoric communities invest significant effort into building a deep watering hole here?
Researchers believe the answer lies in ancient climate conditions. Pollen analysis from the site indicates that the region experienced a period of weather-warming during the Middle Bronze Age. This shift likely altered local water availability, making natural sources less reliable than they appear today.
"One of the things we do wonder is why we have such a feature in an area that is now rich in streams and rivers," Guarino noted in an interview with the BBC. "We know from pollen analysis that during the Middle Bronze Age there was a period of weather-warming. The fact we're finding more of these water holes suggests communities were digging them to access water near their settlements."
A Window into the Past
There is a certain irony in the well’s survival. The same high groundwater levels that may have developed long after the Bronze Age well fell out of use ultimately created the conditions that preserved it. Over time, the rising water table sealed the structure in a protective, oxygen-poor environment, allowing it to remain intact for over three millennia.
Fieldwork at the site has now been completed, and the findings have been shared with local authorities. The recovered timbers are undergoing detailed analysis by specialists, with some pieces selected for long-term conservation. This ensures that this rare glimpse into prehistoric life will be preserved for future study.
The discovery adds a much earlier chapter to the region’s history, which is already known for its Roman and Anglo-Saxon heritage. The wooden well stands as a powerful reminder of how ancient communities adapted to changing climates through practical ingenuity.
