Sheffield City Council is seeking planning permission for preparatory works at Castle Park in the Castlegate area of the city centre, as part of a long-running project to transform the former Castle Market site into a public park showcasing the ruins of Sheffield Castle. The scheme matters because it will bring the remains of the Norman fortress into public view for the first time in centuries, alongside restoring a stretch of the River Sheaf that has been hidden since 1912, marking a significant step in regenerating a historically important but long-neglected part of the city.

The 11th-century castle was built near the confluence of the Rivers Sheaf and Don, the site from which Sheffield itself grew, later boosted by a royal charter granted in 1296 that allowed markets to be held there. Excavations two years ago uncovered far more of the castle than expected, including gatehouse towers, a 12.5-metre-deep well still containing water, a drawbridge, sections of the moat, a 19th-century steelworks built into the castle walls, and a Victorian cobbled passageway, prompting a redesign of the park. The latest planning application covers specialist protective works needed so that an access road can be built through the site without damaging the excavated remains, with the park itself set to open in late 2026.
