The Island - (Hythe End Island)

Right bank residential Island just above Bell Weir Lock, Staines-upon-Thames
The native inhabitant of whom the ancient visiting geographer enquired the name had obviously never been more than half a mile either way along the river - and so when asked what that particular piece of land was called replied that it was 'The Island' (as opposed to Church Island downstream or Magna Carta Island upstream) - and 'The Island' it remained!
More illuminating is the name of its connecting road - 'Hythe End Road'. A Hythe was a landing place or wharf.

The downstream end of the first section of the Lower Thames Flood Prevention scheme is planned to exit on the Right bank above Bell Weir Lock. This will make "The Island" feel more insular than it does already!
