#25 Very useful in case there’s an emergency
This is literally the definitive picture of the “stairway to nowhere”. It looks as though someone wasn’t paying attention and forgot to install a door to go along with the vintage spiral staircase. For that matter, who installs a spiral staircase outside of building? It looks as though the world will never know exactly what was going on in the mind of the contractor at this moment in time. This funny construction fail was probably not expected by the building owners.
