Not so much now, John, more non car owners! If you do come across some wrought iron work, not exclusively balconies, please let me know!
For anyone visiting Cologne in the near future, I can recommend the most beautiful wrought iron fountain, featuring among other things the characters from the fairy tale ‘The elves and the shoemaker’ , Die Heinzelmaennchen von Koeln in good German.
It is a city well worth exploring ( I don’t get paid for this, by the way! Only joking. ) wish I could still travel, as I used to! Bet others have said that too. All the best, Linde
