The Colegio de Doncellas Nobles was a school for girls founded in 1551 in Toledo, Spain, and placed under royal patronage. It is now considered a royal site, under the administration of the Patrimonio Nacional. The girls were admitted to the school between the ages of seven and ten, and received an education. They could exit into marriage with a dowry, or into a convent without a dowry. They had to be of "clean blood", that is, descendants of Old Christian, and therefore not a descendant of someone at odds with the Inquisition, which usually meant Jewish, Muslim, or heretical ancestry.
