Not a Portal
Wouldn’t it have been cool to tell people that you had a portal in your house? It’s almost like stepping inside a sci-fi movie. On the other hand, finding a secret, mysterious portal (or a hole that looks a lot like a portal) can be quite alarming as well. We’re not sure we’d want to get in there to see what’s on the other side.

This looks like a suspiciously random hole someone found in their bathroom, but there’s no need to suspect anything; it’s not a portal, and it’s not a peephole either. Experts on the internet said it’s a fixture that is meant for a chimney. It is likely that some sort of wood stove used to be there before.
