SAN, a town of Spain, Andalucia, in the province and 56 miles S.E. of Cadiz, and 7 N.W. of Gibraltar. It stands on a hill, and consists chiefly of low houses. In the principal square is a town-hall; and the other public buildings are a church and convent, several schools, an hospital, poor-house, and prison. Outside the town is a public walk and a cemetery. Wine, curdage, leather, soap, pottery, &c., are made here, and there is some trade in corn. San Roque was built by the Spaniards in 1704, after their loss of Gibraltar, principally out of the ruins of the ancient Carteia. The climate here is salubrious, and living very cheap. Pop. 7619.
