Gulf of Urabá
In 1502, on another coast of present-day Colombia, near the Gulf of Urabá, Spanish explorers led by Vasco Núñez de Balboa explored and conquered the area near the Atrato River. There they founded Santa María la Antigua del Darién (c. 1509) and the now-vanished town of San Sebastian de Urabá (c. 1508-1510), the first two European settlements on the mainland of the Americas.
