To start the ball rolling,my second favourite is the 'Sail' at the eastern entry to Lagos; my absolute favourite is the 'sky-watchers' at Faro airport - a modern but brilliant piece of art,in my view.How I wish that roundabouts in the U.K. could be as interesting and entertaining as the Portuguese ones !! Look forward to seeing your choices.
