Gibraltar, a promontory of rock, in the S. of Spain, about 2 m. square and over 1400 ft. in height, connected with the mainland by a spit of sand, forming a strong fortress, with a town (25) of the name at the foot of it on the W. side, and with the Strait of Gibraltar on the S., which at its narrowest is 15 m. broad; the rock above the town is a network of batteries, mounted with heavy cannon, and the town itself is a trade entrepôt for N. Africa; the rock has been held as a stronghold by the British since 1704.
