Archaeologists have completed a new survey of a medieval well at Sheffield Castle, revealing fresh details about a structure that once supplied water to the castle’s inhabitants during both daily life and wartime.
The work was carried out by Wessex Archaeology alongside FlyThru during excavations connected to Sheffield City Council’s Castlegate Regeneration Project. Funding for the wider scheme has come from the South Yorkshire Mayoral Combined Authority.
The well sits inside the Norman motte, the raised mound at the heart of the former castle complex. Archaeologists say it would have been one of the most important features within the fortress, supplying fresh water to soldiers, workers and residents living behind the castle walls.
During the English Civil War, access to water became especially important. When Sheffield Castle came under siege in the 1640s, those sheltering inside would have relied on the well while enemy forces surrounded the site.
The shaft measures around 12.5 metres deep. Stone lining survives near the top before the well cuts down through solid bedrock. Although the structure has remained hidden for centuries, the latest survey has allowed researchers to examine it in detail without disturbing the remains.
To record the interior, a drone protected by a metal cage was lowered into the shaft. As it descended, it captured hundreds of photographs that were later combined to build a detailed 3D model. The images showed surviving construction details and confirmed that water still remains at the bottom of the well.
Ashley Tuck, Research Manager at Wessex Archaeology, said the discovery offers a direct link to the castle’s past.
“This was an exciting day at Sheffield Castle,” he said. “The medieval well would have been indispensable for the people who lived and worked in the castle day-to-day and especially so during times of siege. With an attacking army outside the castle walls, those inside would have needed water within the castle boundaries for their survival.”
Sheffield Castle once stood at the meeting point of the Rivers Don and Sheaf and was one of the region’s main medieval strongholds. Built shortly after the Norman Conquest, it remained an important centre of power for centuries before being dismantled after the Civil War.
Although little can now be seen above ground, excavations over recent years have uncovered walls, buildings and other features linked to the castle complex beneath the modern city centre. Archaeologists believe the discoveries are helping to reshape understanding of Sheffield’s medieval history.
The current excavation is being led by Wessex Archaeology while engineering specialists Aureos are overseeing work taking place alongside construction activity on the site.
The Castlegate Regeneration Project aims to revive one of the oldest parts of Sheffield by opening up historic areas and creating new public spaces. Archaeological work carried out during the redevelopment is expected to form a major part of that process.
Researchers will now use the 3D survey to study the well more closely and examine how it was built and maintained. The digital model also provides a permanent record of a feature that few people have ever seen.
For archaeologists, the well offers rare physical evidence of how life continued inside Sheffield Castle during periods of conflict and uncertainty centuries ago.
