Works on the beach near Parc Eden Roc

The usual turn-around spot on my regular walk is at a 'private' housing estate called Parc Eden Roc. I'm not sure how or why it's private but I haven't been arrested yet!
One day in mid October I arrived to find lots of activity just above the beach.

Piles of wooden stakes...

...and bales of straw. 

Down on the beach things start to become clearer...

...with diggers creating trenches and other machines pushing the stakes into the sand in rows either side of the trench...

...to be followed by positioning of the bales of straw between the rows of stakes.

A couple of weeks later and things are looking complete...

...but not everywhere. There's still work to be done.

Five weeks later, the machines have gone and the beach is ready for the next spring tide ('grande marée').
