  • No, it predates the formal invention of roundabouts. It doesn't actually have any roundabout carriageway markings (i.e., give way lines to the circulatory carriageway), so you just need to take your cue from that. There are a number of locations like this in Paris, e.g. the Franklin D. Roosevelt junction further down the Champs-Élysées, or the Place de la Concorde. I suspect that there may be heritage reasons for the fact that they haven't been converted into formal roundabouts (or 'longabouts' in the case of the Concorde), despite having the shape and appearance.
