The Parliament created the National Archives of Andorra by regulation in 1975 in order to provide a documentary base for education and historical research, while guaranteeing and safeguarding the documentary heritage of Andorra.

The facilities of the National Archive of Andorra have been housed in the Prada Casadet building since 1985.

Since November 1989, the Administration of Archives of Andorra forms part of the International Council on Archives (ICA/CIA), the foremost international body in matters of archives, as a member of Group A, the category for central directorates of archives or institutions with authority over the set of archives of a country.

Since 1995, the Administration of Archives of Andorra forms part of the International Association of Sound and Audiovisual Archives (IASA).

The archival model of the Central Administration of Andorra was defined and implemented in 1997. The archival system in Andorra is structured, within the framework of the Archives Service of the Ministry of Culture, as follows: National Archive of Andorra, Administrative Archive, Management Archives and Central Archives of the Government of Andorra.
