Vizcaya is a castle of the Kingdom of Castille and the fief of Don Diego López de Haro. Castillian Footmen and Castillian Pages can be recruited inside its walls, provided the player is of noble condition and serves as a vassal of a faction (or is the ruler of its own).

Its related village is San Sebastián.

Vizcaya is located in the north-eastern iberian coast, in the southern shore of the Bay of Biscay, not far from the border between Castille and Navarre.
