About the Key Window design

At the center sits a small open square, tied by four short bars to the scrollwork around it. Four squared spiral hooks curl inward from there, mirrored top to bottom and left to right so each pair faces the other across the middle. Toward the border, straight bars carve the ground into a wide slot above and below, a tall slot on each side, and a small rectangular pane tucked into every corner.
