Here’s a clearer picture, hot off the press.

Oh, sorry. I see them every day so I forget that others don’t have context.

It’s a set of bars designed to stop cars coming up a pedestrian lane and / or slow down bicycles at the intersection. There are two sets of bars so you have to sort of swerve through them.

Typically, as I am walking towards the sea in this picture, I grab the bars to swing right towards the town. I recently noticed that I’m not alone because one side (for folks turning right) is worn down by the friction of those hands grabbing to swing right.
