Big hole in wall but it doesn't fall down?

You'll have to watch this during daylight hours. Notice the enormous hole in the wall, yet there's a restaurant running above it?! What's holding that up?

I wonder if it's only the outer rendering that's flaked off, and there's a solid breezeblock wall behind it which is providing the structural strength. Even so, it's amazing that the rendering is still supporting its own weight.

I think you mean concrete block. Breezeblock is the stuff that weighs virtually nothing and you can smash it with your fist. It's only used for internal walls.

But won't provide structural strength.

Surely the brick in the middle of the top of the hole will fall, and so on.

The hole is holding up the brick?

Are you insane? If you remove the hole, whatever was above it is now above empty space and is therefore subject to the forces of gravity.
