Well there was “the great storm” which completed the silting up of the River Zwin which had made Bruges a great seaport.
It had gradually been silting up for years but the storm at the same time as
the one mentioned if memory serves me right,I will have to check,finished
the job.
However that meant Bruges did not develop like Antwerp for example and we have the lovely town almost trapped in time.
The marshes left are now a fantastic bird sanctuary and the sleepy towns of Damme , Sluis and Oostkerke fell asleep.
The irony was that a great storm in the eleven hundreds had opened up the river .
I wonder if the “tsunami” was anything to do with the storm that silted up
the Zwin.
