El Cotillo town sea rocks

[George Jackson]

I was in El Cotillo town this afternoon and the tide was only covering some of the rocks. I saw some "squares" in the sea which appear to be man made and look like rock. Anyone know what they are please.
I have seen something similar in Almeria, where small areas were made of rocks at the edge of the sea, many years ago, to catch fish when the tide went out.
I will try to take photos next time I see it.
Thanks in advance for any replies.ò

Hi George, where exactly did you see it, in the old harbor part?

No, it was in the bay, just below the Vaca Azul restaurant. Don't think this is the old harbour. ... think that us further around the coast near NaNa place. The squares are quite easy to see when the tide is going out.
