The Museum of Cádiz collections have diverse origins.
The works in the Archaeological Section were discoveries made by chance, such as the masculine Phoenician anthropoid sarcophagus, donations of historical collections by individuals, particularly rich in numismatic findings, or scientific archaeological excavations. These excavations are the source of most of the objects in the section and they represent significant growth in the future. The main enclaves from which some of the unique pieces of the museum have come are: with regard to the prehistoric findings, the various caves and dolmens in the province; the Phoenician and Roman findings originate from Cádiz itself, and from the Roman cities of Baelo Claudia (Tarifa) and Carissa Aurelia (Espera). The medieval period is the one which is least represented, corresponding to the historic evolution of the city.
The works gathered by the Academy of Fine Arts Cádiz throughout the 19th and 20th century constitute the core of the Fine Arts Section. This initial nucleus has grown thanks to purchases made by the Junta de Andalucía, in particular, over the last few years, with regard to the addition of works to the Contemporary Art collection. Likewise, the donations from individuals have also been of note over recent years, in particular, a work by Ignacio Zuloaga Portrait of Micaela Aramburu Picardo, donated by the family of Aramburu Picardo in 2003.
Finally, the Tía Norica puppet collection was acquired by the State.
