Calahorra is a castle of the Kingdom of Castille and the fief of King Alfonso the Noble. 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 Logroño.

Calahorra is located in the northern-central plateau of the Iberian Peninsula, pretty close to the source of River Ebro, right on the border between Castille and Navarre.
