My question is how can all of these bricks be supported by the thin columns on either side? How can there be that much empty space under all of the bricks that the arrow is going through? Looking at it I am under the impression that it should collapse because there are no bricks underneath to support such a huge area. It also does not look like there is a beam or anything else directly under the rectangle of breaks so they should fall down.
In the second image, there is a stone support to support the weight of the bricks above but the first image does not.
The third image looks like it should collapse as well.
