Q: The Portuguese found the island uninhabited, with an abundance of trees and fresh water. They imported livestock, fruit trees and vegetables, and built a chapel and one or two houses. Though they formed no permanent settlement, the island was an important rendezvous point and source of food for ships travelling from Asia to Europe, and frequently sick mariners were left on the island to recover, before taking passage on the next ship to call on the island.
