When I was teaching in S. João da Madeira almost 20 years ago, it was known as the "roundabout capital" of Portugal. Roundabouts were beginning to replace the traditional intersections with traffic lights. There seemed to be a "roundabout madness" and buses and other longer vehicles had difficulty negotiating some of the ones built where there just wasn't enough space.
Now every town has many and besides being useful, they lend themselves to artistic efforts. The middle of roundabouts vary from the simple circle to the weird and wonderful. The one in this picture must be a nightmare for the gardener. How does he manage to keep the grass trimmed?
Don't you think the sculpture looks a little lost there?
