An experienced carpenter could probably take one glance at this door and tell when it was made. Not being such a carpenter, I can only guess how old this door is given that I found it in the medieval Lindenhof quarter of Zürich. The lock and handle don't look old to me, but I'm guessing they could easily have been replaced. And I don't know. Are those nail holes? If so, then the door certainly couldn't be too old. What do you think?
