Went to a camping in the Laurentians in Québec (Ste-Agathe) and there were those things near some camp sites. The sites are only accessible by footpaths. No car access. And if you bring a bike, you have to walk it up a hill, so I doubt they are bike racks.
EDIT: I have sent an email to the park and they have been kind enough to reply. It's just a type of fireplace with a grate. They didn't give more info than just this. Thanks to everyone for pitching in!
Looks like a grill design to me.
If it was a grill, the concrete would be discolored.
Why?
EDIT: Oh, because of the fire. I was thinking grill like the grill we put on drains to stop leaves
Only if it's been used recently.
How the hell would that work?
Fire goes under the bars, food goes on the bars.
You know, like a grill.
What kind of food is going to sit on that? You cooking a whole leg of something?
You could probably get a tomahawk steak to work on there, or a whole, bone in long pig thigh.
Something wider than the gap between the bars, I'd assume. Or a pan.
You've never grilled anything, have you?
I have grilled many things.
Have you ever grilled anything on a contraption like in OP's pic?
Maybe!
