White plaque № 56719

This white commemorative plaque records: In pre-historic times, the Itchen flowed in two main channels in the centre of the river valley, near the Cathedral. Following the foundation of the Roman town, about 70 AD, this new artificial channel was created. This both reduced the chance of flooding in the town centre and provided an eastern defensive moat. In the medieval period, the river was nearly twice as wide as today. Recorded plaque organisation: Winchester City Council.

The artificial channel near the Cathedral in the Roman town, created around 70 AD, served to prevent flooding and act as a defensive moat, showcasing early urban planning and engineering skills. The medieval width of the Itchen, nearly twice its current size, reflects significant changes in local geography and human intervention over time.
