The mill sits on the site of a royal mill mentioned in the Domesday Book of 1086.
The current machinery is powered by a restored undershot waterwheel.
The River Itchen, which powers the mill, is a rare chalk stream renowned for its clear water and high biodiversity.
The mill was saved from demolition in the 1970s and restored by the City of Winchester Trust before being taken over by the National Trust.
During the milling process, the stones rotate at a specific speed to prevent the flour from overheating, which preserves nutrients.
The mill building historically served as a residence for the miller and his family on the upper floors.
It is one of the few places in the UK where flour is still produced using water power in a town-center location.
Winchester City Mill is a fully operational 18th-century watermill powered by the River Itchen. Located on the site of a Saxon mill dating back to at least the 11th century, the current structure was rebuilt in 1743. It serves as a working flour mill where visitors can watch live milling demonstrations using traditional millstones. The site functions as a National Trust property dedicated to preserving milling heritage and local biodiversity. The building features an internal waterwheel that drives the machinery while overlooking the riverbanks. It integrates a visitor center and exhibition space explaining the mill's historical significance in the city of Winchester. The mill processes organic wheat to produce stone-ground flour available for purchase on-site.

Check the daily milling schedule at the entrance upon arrival to catch a live demonstration.
Watch for otters in the River Itchen from the viewing area, as they are frequently spotted near the mill's foundations.
Purchase a bag of freshly milled flour to take home.
Do not expect a high-speed production line; this is a traditional, slow-paced craft process.
Operating days can vary seasonally; check local National Trust site updates for mid-week closures during winter months.
