Israel State Archives (Hebrew: גנזך המדינה, Ganzakh HaMedina) is the national archive of Israel, located in Jerusalem. The archive houses some 400 million documents, maps, stamps, audio tapes, video clips, photographs and special publications.
The archive was established in 1949 to house historical records of government administrations from the Ottoman era to the end of the British Mandate and document the newly established State of Israel.
In 2008, the Israel Museum mounted "Blue and White Pages," a joint exhibit with the Israel State Archives featuring documents relating to the history of the Jewish people from ancient times until the present.
In 2012 the headquarters of the archive were closed until further notice after it was found that the building had been operating without the appropriate permit for the previous 19 years. According to a source quoted by Haaretz, obtaining a permit and reopening of the archive will take a matter of months. Access to the archives for researches will be halted until the building reopens.
