Spike sent me this picture of Abingdon – five years ago, showing the River Thames having burst its banks. Thankyou to him.
There is a bigger version (here …)
Last time the River Thames broke its banks was in April 2018. The Thames at War event at the Lock was postponed as a consequence. I read in the Oxford Mail that the event will be held instead on April 14th, 2019.
The WWII Pillbox is between Marcham and Abingdon.
