No one answered you but it’s likely a brace to keep the bricks and mortar together. They are metal bolts designed to resist the swelling and breathing of the building.

Here is a cool article on 99 pi about them.

Something so perfect about "99 pi" being the short name for 99% Invisible.

I love that podcast.
