Exe Island was the early industrial area of
Exeter,
England, and was an area of marshland between the city walls and the
River Exe, reclaimed by the construction of a series of
leats, or water courses, possibly from as early as the 10th century. Of these, the Higher Leat still exists. It created Exe Island, which was a separate manor belonging to the Courtenays,
Earls of Devon.
