This giant padlock is supposed to be the world’s largest working lock. It’s tough to discern its actual size, but looks like it’s bigger than a grown man.
The lock is currently placed in a park in Gujranwala, Pakistan, probably because they haven’t built a gate large enough to use it.
Maybe they should consider exporting it to Mordor for the black gates. I’m sure a troll would have no trouble turning the giant key. link
