It is strange to me to see a fence so close to the sea!Thank you for sharing at https://image-in-ing.blogspot.com/2021/09/the-sistine-chapel-exhibit.html
I think the fence is mainly there to keep people off the vegetation on the sand dunes which protect them from erosion.
Good of this one to pose for you.
