1568 sighted the Spanish navigator Alvaro de Mendaña de Neyra northwest before Santa Isabel a large island, which he called San Marcos. However, he did not land on the island, which is probably were Choiseul. Due to a mapping error, this was only rediscovered in 1768 by the French explorer Louis Antoine de Bougainville for Europe. He named it after the then French Foreign Minister Étienne- François de Choiseul.
