FUENTE-RRABIA, a city and fortification of Spain, in the province of Guipuzcoa, at the mouth of the Bidasoa, on the frontier towards France. The harbour has a bar at its mouth, which forbids the entrance of vessels except at high tide; and even then those only from forty to fifty tons burden can enter. It was made a place of considerable note by the operations of that war which preceded the celebrated battle of Roncesvalles. Its latitude is 43. 21. 36. N. and its longitude 1. 16. 7. west from London. It contains a population of 1700 souls.
