Colegio de San Juan de Letran, Mexico City — the crown's schools for mestizo children

A school opened in Mexico City around 1547 for the mestizo sons of Spaniards, with a parallel house for mestiza girls, both under royal patronage and both still being inspected and audited by law two centuries later. The viceroy who reports the foundation states its motive in the same sentence as its charity: the emperor and empress had ordered many times that these children be gathered in, "porque andaban muchos dellos perdidos entre los indios".
