Ilchester was a Roman garrison town, built at the point where the Fosse Way crossed the River Ivel, and there is evidence that the Romans built quays on the river.
The Parrett Navigation Company was formed to improve river navigation on the River Parrett, Ivelchester and Langport Navigation and linked waterways.
