Queretaro, a state and city of Mexico, North America, The former has an area of 3,400 square miles, occupying a central plateau of the Cordilleras and being broken up by rugged mountains. The valleys are fertile, producing grain and cotton, and feeding large numbers of sheep and cattle. Gold, silver, antimony, mercury, and other metals are worked, but not on a great scale. The city stands high, and is connected by railway with Mexico, 152 miles distant. The Hercules cotton-mills are the largest in the republic, and the woollen, leather, soap, and wood-carving industries also prosper. The Emperor Maximilian (q.v.) was executed here in 1867.
