A foundling hospital was originally an institution for the reception of foundlings, i.e., children who had been abandoned or exposed, and left for the public to find and save. A foundling hospital was not necessarily a medical hospital, but more commonly a children's home, offering shelter and education to foundlings.
The antecedents of such institutions was the practice of the Catholic Church providing a system of relief, children being left (jactati) in marble shells at the church doors, and tended first by the matricularii or male nurses, and then by the nutricarii or foster parents. But it was in the 7th and 8th centuries that definite institutions for foundlings were established in such towns as Trèves, Milan and Montpellier.
