Thanks all for the comments, much appreciated and I apologise for the belated reply.
Lens is a Sigma 17-70mm non HSM model.
The structure you can see is a rocky cliff face.
This was shot on a different day but it shows more of the cliff face:
1.
Where I live is weird as on the other side of that cliff is land, you can just see the breaks in the cliff in the background that allows you access to the beach:
2.
To the right of the above picture just out of sight we have a fresh water natural lagoon:

and then weirdly to the left of pic 2 is a natural sand dune area and then an old quarry that's now a fresh water small lake and that's backdropped against the cliff as in pic 1! So much here but a weird set up lol !!
