Fagundes explored the islands of St Paul near Cape Breton, Sable Island, Penguin Island, Burgeo, and Saint Pierre and Miquelon which he named the islands of Eleven Thousand Virgins in honor of Saint Ursula.
King Manuel I of Portugal gave Fagundes exclusive rights and ownership of his discoveries on March 13th 1521.
Between 1521 and 1525, Fagundes tried to establish a colony in Nova Scotia but little else is known.
