To the left of the headland discussed in the previous shot is The Island Archway. That's the top of it that we can see in this shot. Where's the archway? Well, it did have one connecting it to what is now another stack of limestone closer in to shore. However that archway collapsed in 2009 leaving two separate piles.

What you're seeing here is now an island without an archway, but nobody has come up with a better name yet.
