Which fortified settlement let the conquistador Alonso de Ojeda in 1509 build on the Gulf of Darién, the first Spanish one on mainland South America?

In November 1509 Alonso de Ojeda departed Santo Domingo with 225 men to take up his governorship in New Andalusia (Colombia). After being repulsed in a battle with indigenous tribes in the Cartagena area, Ojeda landed on the east coast of the Gulf of Urabá (close to the modern border with Panama) and founded the settlement of San Sebastián de Urabá. However, the native inhabitants were hostile and-after eight months of conflict, with no reinforcements in sight and only 42 colonists still alive-the settlement was abandoned.

Gulf of Darién, Spanish Golfo De Darién, triangular southernmost extension of the Caribbean Sea, bounded by Panama on the southwest and by Colombia on the southeast and east. The inner section, which is called the Gulf of Urabá, is a shallow, mangrove-lined arm lying between Caribana Point and Cape Tiburón, Colombia.
