The land was purchased by the University of Oxford during the expansion of the Oxford University Parks between 1860 and 1865. A footpath, Mesopotamia Walk, laid out in 1865 runs along the centre of the spur to Kings Mill.[2]
The Domesday Book records a watermill on this site and milling continued until 1825; one level of the river was once the mill stream.[3] From 1914, attempts were made to introduce wild ducks and geese to the area, which proved fruitless due to a predatory otter population. Until 1926, a ferry operated from a point halfway along the Walk, when it was replaced by a footbridge.
