Why do brick buildings have vertical bricks above the windows?


Sometimes it’s shaped like an arch. Is this just for aesthetics, or is it structurally necessary?

Friction. Vertical bricks have a longer edge to joint to the next brick. A horizontal brick with no support below it would only have a small area at the side to help it stay there. Vertical bricks are also held better with less ability to wobble in the direction the wall runs.

So they are just better at staying in place. For the rest of the wall being horizontal helps keep the bricks from pulling apart and the wall cracking.
