The Archaeology Museum in Cagliari is part of the Sardinian Museum Network and it shares its aims and mission, fully complying with the definition of a museum given by the International Council of Museums (ICOM): “A museum is a non-profit, permanent institution in the service of society and its development, open to the public, which acquires, conserves, researches, communicates and exhibits the tangible and intangible heritage of humanity and its environment for the purposes of education, study and enjoyment.” The National Archaeology Museum in Cagliari is a liquid museum. It is constantly changing in order to be more and more inclusive in every way, including in physical, sensory, cognitive and digital terms. It is a museum for children, the elderly, visitors from other countries and disabled people, so it is chameleonic and liquid: it can take on different shapes and sizes to cater to the needs of each of its visitors. It is a museum that uses sustainable and renewable technology to aid understanding of the heritage that it showcases. It is a museum that is dedicated to growing together with its visitors, in order to make a habit of turning its tales into unique experiences. It is a museum that also serves as a social setting in its home city, promoting educational and recreational activities and events. It is a museum whose mission is to preserve and present the archaeological heritage of Sardinia. It is a museum with a strong sense of the importance of connecting with its homeland and the rest of the world, especially the areas on the shores of the Mediterranean, where different people and cultures come together.
