In this century, museums face the great challenge of reinventing themselves and rethinking their projection to attract new audiences, communicate and disseminate the tangible and intangible heritage of humanity, which is kept in their spaces by numerous specialists and restorers.

As is the case every year, 18 May is International Museum Day, a commemoration established by the General Assembly of the International Council of Museums (ICOM) to highlight the importance of the role played by these spaces in safeguarding and disseminating the historical, scientific, cultural, artistic, technical, and archaeological memory, and so on.

Museums are defined as democratizing, inclusive and polyphonic places for critical dialogue about the past and the future. Although their role in research, preservation and communication is emphasized, their role in addressing the conflicts and challenges of the present and the future is also recognized.

Museum collections hold artifacts and specimens that safeguard the most diverse memories for future generations, and ensure equal rights and accessibility of heritage for all peoples.

It should be emphasized that museums are not-for-profit and work in active partnership with diverse communities to collect, preserve, research, interpret, exhibit, and broaden understandings of the world, its societies, and relevant personalities.

Some experts say that the greatest challenge for museums in the 21st century is their audiences, as well as expanding their horizons to include new actors and their actions on digital platforms in order to streamline and socialize their collections, although they cannot abandon their fundamental activity, which is to preserve, conserve and promote the heritage they possess.

It is noteworthy that these centers are alternative places that allow for non-formal education; it is also necessary that their institutional discourse is linked to the communities as a bridge to feedback.

During the present COVID-19 pandemic, museums around the world have reinvented and rethought their work, strengthening some of the tools they were already using. In this very particular context, they have enhanced the digital scenario and the positioning of a wide variety of content on social media, which has made it possible to increase the relationship with different audiences, both regulars and neophytes.
