The river just over a hundred years ago had a very jagged bank.
It was still very jagged when this picture was taken. Many Thanks to Captainkaos2 for this view showing the old changing rooms on tiger island when it was the town’s bathing place.
The banks of the River Thames either side of Abingdon Bridge now have a well defined curve and have been reinforced to keep their shape, and allow mooring.
Further upstream and downstream the banks are still allowed to erode giving them a jagged appearance.
