These were at the airport in Split. I presume that they also capture rainwater, probably a hot commodity in that dry country. I love the way they are beautiful and multi-functional, as they also provide shade.Brač where we spent nine days with my beloved's family meant a ferry ride. Unlike the one in the picture, the ferry also took cars, trucks, and motorcycle, and it had an opening in one end for the vehicles to drive on and an opening at the other end for them to drive off. No turning around needed! I thought that was pretty spiffy.
