I’d like to see a picture of that lighthouse from 40 years ago. I’d bet it would show an identical sea level to the current pic.

That’s the Poolbeg lighthouse in Dublin Bay. It’s 4miles out and connected by a stone causeway. It was built in the mid 1700’s.
All in all, I’d say things are doing fine some three hundred years on, despite what a stormy picture at high tide would seem to show.

It’s the Poolbeg lighthouse. You can google images. It’s built almost level with the sea, not on a high rocky cliff. This picture was obviously taken during a storm at high tide. They are desperate to deceive.
