The San Vicente de Paul Hospital was the first Clinical Hospital of the University of Chile and was located at the same place of present School of Medicine. The School are contains several old buildings, which are probably remains of the San Vicente de Paul Hospital. After a careful study of the current plans of the Faculty of Medicine of the University of Chile and those of the San Vicente de Paul Hospital, and after checking measurements on the actual site, we were able to demonstrate that two and a half clinical rooms of the original building and some parts of the old laundry still remain intact. At present, these constructions are being used as storerooms, student's union offices, and other activities. We expect that this article may contribute to improve the knowledge of our roots by our own as well as by future generations and that it may inspire our authorities to take care and preserve this important patrimonial remains of our national medicine
