Gm my friends,

Have a wonderful Thursday.

Good Morning Arjan! This is so fascinating! Was it used to carry water?

how cool it is! I can imagine it! Thanks for sharing Arjan!

To be fair, I am not 100% sure, but there was a similar object on the other side of the river. It's at the outer bounds of the Chantilly castle. I think it was a chain mechanism. The chain would be across the river so boats could not come closer to the castle. It would be lowered to allow access.
