I collect roundabouts – by which I mean photographically rather than having a collection in my back garden. I got interested in roundabouts about 14 years ago, firstly as a teaching aid for island biogeography (see Teaching Matters) and then as part of my research. The French have some great roundabouts, see below for a fine example of a landlocked island.
Here are a few more fine roundabouts.
