Sea Goddess Info

We came across a statue that was near the sea and clifftops. I called it a sea goddess but I have no idea what it is and what it actually represents. The statue was behind a locked gate which we had to climb over to get some good photos of it. I was kind of taken by seeing it as it was in a hidden corner of fields and not something I don’t see everyday. I have no idea what it’s made of but it in cased in stone.
