Hagrid's Hut, to be more specific, now under construction under the old Flying Unicorn ride. It's not much to look at at this point, at least viewed closely in the Dueling Dragons queue. However, it's a sign of progress for this extravagant Islands of Adventure project.

Here's the movie version of the hut.

Here's the construction photos from behind the Hogwarts clearing.

And an outside look.

Also, directly in front of the Hogwarts building, a queue design of some kind (perhaps I'm way off on that guess) has formed over the last month.

Last month.

This past weekend.

And here are the latest views of Hogwarts.

And the former Enchanted Oak area (complete with bored teamster).
