The sea wall was breached a while ago and never repaired properly. A storm last month wrecked the temporary repair, and so far it looks like it's been decided not to fix it, but let nature take its course.
I think I'll visit each month (as I start retirement tomorrow - so should have time!) to see what damage Mother Nature wreaks to the wall and the nature reserve it will flood twice daily!
Congratulations on your retirement too :)
GREAT photo!
