During more than 100 years of history, the collaboration between civil society, local artists and public institutions has enabled the museum to gather an extensive collection, considered one of the most important and diverse of all Spain. Its creation is unique taking into account the importance of bequests and donations from diverse patrons and benefactors, as well as the continuous effort of the museum itself to expand through major acquisitions. Since its inception, the interest in establishing a representative artistic compendium has allowed to refine the selection criteria, and, as a result, the museum can offer and present a panoramic lengthy art history to its visitors.
