Once upon a time I saw a very old OS map of Exeter in the Treasures of the British Library exhibition. Now through the miracle of Google, I know that it was the Drawing for the first edition Ordnance Survey map of Exeter. 1801 Maps OSD 40.(3).
As a birthday treat, I promised myself a walk down Woodwater Lane, from home to water to wood to home again. A satisfying experimentation in exploring the present day.
