a port-town of Andalusia, in Spain, subject to Great Britain: W. long. 6°, and N. lat. 36°.

It stands at the foot of mount Calpe, one of Hercules's pillars, about fifteen miles north of Ceuta, in Africa, from which it is divided by the Straight, to which it gives name. It is built on a rock, in a peninsula, and can only be approached on the land-side by a very narrow passage between the mountain and the sea: across this passage the Spaniards have drawn a line, and fortified it, to prevent the garrison's having any communication with the country.

The Straits of Gibraltar are about twenty-four miles long, and fifteen broad.
