History
In 1577, José Luis Carvajal y de la Cueva founded the village of Saltillo; in the same year, he also founded Santa Lucía, now called Monterrey, and discovered the mines of San Gregorio, located in what is now called Cerralvo. On May 31, 1579, Luis Carvajal signed an agreement with King Philip II of Spain to pacify the region and to establish the state of Nuevo León; the contract authorized him to do this in an area that did not exceed 200 leagues on a side.

The first Spanish settlement in Nuevo León took place in 1582 in Cerralvo, which thus included the first capital of the state. In 1630, this settlement was renamed Villa de San Gregorio de Cerralvo, after the fifteenth Viceroy of New Spain, Rodrigo Pacheco y Osorio, marqués de Cerralvo.

The municipality was settled in order to exploit mineral resources, including lead, and to sell Indians to the Spanish.

Cerralvo is home to the national park El Sabinal, which, with an area of 8 hectares, is the smallest national park in Mexico.
