La Quemada was inhabited between about AD 300 and 1200, and it is estimated to have peaked between 500 and 900 with as many as 3000 inhabitants. From around 400 it was part of a regional trade network linked to Teotihuacán, but fortifications suggest that La Quemada later tried to dominate trade in this region. The impressive ruins stand on a hill overlooking a broad valley 45km south of Zacatecas, 2.5km east of the Zacatecas–Guadalajara road.
