Gulf of Urabá
The Governor of Nueva Andalucía was Alonso de Ojeda and the mayor of Castilla del Oro was Diego de Nicuesa, who became the first governor of the Isthmus of Panama. Diego de Nicuesa founded Nombre de Dios in 1510. Martin Fernandez de Enciso founded Santa Maria la Antigua del Darién, west of the Gulf of Urabá, in September 1510 on the advice of Vasco Núñez de Balboa, who had arrived at those lands earlier with Rodrigo de Bastidas.
