This is a 1971 map of Bertioga. The blue circle shows the location of the Itatinga Hydroelectric Power Plant, while the red one shows the port where the tramway begins. The green rectangles shows decauville railways, used to transport bananas from the farms to little ports, where they were put into boats and transported to Santos. By the way, could somebody tell me if they still exists? Apparently not, as these banana farms disappeared or became very small.
