24 Horas Street is a glass-roofed arcade in central Curitiba, created as a modern urban passage lined with food and small shops. It is more interesting as a piece of city planning than as a shopping destination, showing Curitiba's long habit of turning infrastructure into civic theatre.
The name promises round-the-clock life, though opening patterns have changed over time. Drop in while walking the centre, especially if you are interested in how Curitiba presents itself as orderly, designed, and a little experimental.
