The artifacts and objects that are part of the collections of the Museum Center Dr. João Dias belong to two distinct collections, but  complementary; the Holy House of Mercy collection, basically made up of pieces of hospital furniture, and the Dias family collection, made up mainly of medical and surgical objects, photographs and a small specialty library. These two collections comprise a vast set of artifacts and objects that show the history of medical care in Alcoutim and the practice of medicine by the honorable Dr. João Dias.
