MONTEREY, a town of Mexico, capital of the state of New Leon, is situated on the Tigre, at the head of an extensive and picturesque valley, 85 miles E. by N. of Saltillo. The town is well built and paved, most of the houses being in the Moorish style, with flat roofs. The climate is mild and healthy, and there are gold, silver, and lead mines in the neighbourhood. Monterey is well fortified, and offered some resistance to the invading army of General Taylor in 1846; but after an assault of three days, it surrendered on honourable terms. Pop. about 13,000.
