A silhouetted image of the ruins of a dock near Vila do Maio. Until the 19th century the island was a large exporter of salt that was mined on the island. Tarrifs introduced by Brazil in the 19th century, which was the principle market for the island salt business, effectively killed the business. Ruins like these are reminders of the islands once bustling economy.https://digitalcommons.ric.edu/baxter_gallery/1835/thumbnail.jp
