This is one of those places. The canal flows over the Sauldre on a bridge. Pretty cool, eh? These days people can rent old canal barges (motorized) and spend the day on a section of the canal. I'm not sure how far you can take a boat in either direction as there are some places where the canal has been filled in.
On this day we saw two boats tied up on the banks, their occupants enjoying picnic lunches. One of the parties finished their lunch while we were there and drove their boat over the bridge. I was under the bridge when it happened, so I didn't get photos of that.
I went to Google maps and captured an aerial view of this place. In the image below, the Cher River is on the bottom, flowing from right to left. The smaller Sauldre River joins the Cher and just upstream from the confluence you can see the canal bridge crossing.
