Riddle: There is an ancient invention, still used in some parts of the world today, that allows people to see through walls. What is it ?
Answer: A window.
Hint: The “wall” isn’t solid all the way through.
Why this answer works
A window is literally an opening in a wall—often filled with transparent material—so you can “see through” the wall while it remains part of the structure.
Fun fact
The earliest glass windows date back to ancient Rome; before that, people used oiled paper, thin stone like alabaster, or latticework to let in light.

FAQ
Is “door” valid?
Not really—a door lets you look through only when it’s open; a window is explicitly for seeing through the wall.
Why not “periscope”?
It lets you see around obstacles, but it isn’t an ancient wall fixture like a window.
