The Israel Antiquities Authority has expanded the role of the Conservation
Department (Minhal Shimur). This initiative is an outgrowth of the IAA’s
role in safeguarding the cultural assets and built heritage in Israel. The
IAA will act to strengthen the status of the Conservation Department as
the leading professional body that acts to formulate expert standards and
to promote supervision of the conservation processes, professional
training and the assimilation of conservation education.
Bet She‘arim Ben Gurion Airport Zefat

The Conservation Department will advance the preservation of the
cultural heritage in Israel from a national point of view that encompasses
the totality of its values. This heritage is a mosaic of cultures that have
existed in the region from the dawn of humanity until the present. It is
shared by many communities and therefore a high degree of sensitivity is
required in the treatment of it.

Migdal Tzedek
Jerusalem
Bet She’an

The Conservation Department will formulate a policy for the treatment
of the cultural heritage assets in Israel basing it on the Antiquities Law,
professional ethics and the accepted conservation principles in the
world. This policy will make it possible to direct the bodies that are
involved in conservation activity in Israel – public authorities, site
managers, researchers, documenters, planners, conservators and
educators – in assimilating a high degree of professional standards.

The Conservation Department manifests the IAA’s obligation to
establish a body that will lead the way in the field of conservation in
Israel, as an integral part of the responsibility of the state to the
cultural heritage in its territory.
