At the end of the Mexico-Tenochtitlan Conquest, Hernán Cortés began the construction of the hospital known as “El de la limpia Concepción de Nuestra Señora,” at the place where he had first met Moctezuma.
Starting in 1524 this hospital was known as Hospital de Jesús Nazareno (II). It was located at calle 20 de Noviembre 86, Colonia centro, Mexico City, and was the first hospital in Mexico.
Only European Spanish patients could receive care at this hospital, which was home to the earliest professional physicians coming to the Americas from Spain.
In its early days, this hospital admitted about 400 patients annually, and it did not provide care for mental disorders or to patients suffering from syphilis or leprosy. This same facility currently provides care for an average of 5,000 patients per month.
