Temascaltepec
Temascaltepec lies in the mountains southwest of the Valley of Toluca, where wooded uplands fall toward warmer ravines. Its district became one of the gold and silver mining regions of New Spain. Spanish mining began in the sixteenth century, and the villa grew around the workings and the processing estates that served them. By 1819 the district had numerous haciendas de beneficio, where ore was treated to recover its precious metals.
