a city and fortification of Spain, in the province of Guipuzcoa, at the mouth of the Bidassoa, 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.
