It’s possible that your kitchen or hallway has a little built-in shelf if it’s an older house, or basically any house constructed in the early to mid-1900s.
It’s possible that you didn’t give this much thought or you puzzled why it was there. Indeed, there was a purpose behind its placement!
That little shelf is called a phone niche. Before cellphones, people used landlines to communicate. Doesn’t that just seem like so long ago now?
Many homes were built with one phone niche which would house the telephone. Many even had a tiny ledge or drawer above or below the phone to hold address books or phone books. Even the concept of an address book seems so ancient now!
