During this period of twenty years, scientific research on archaeology both on tangible and intangible Cultural Heritage accelerated thanks to the establishment, within the CNR, of numerous scientific research institutes on Cultural Heritage. In 1970, the Institute for Etruscan-Italian archaeology was born in Rome, acquiring the studies of the Centre for Etruscan-Italian archaeology (1968).

In 1978, in the same city, an operational unit of the CNR, named Service for Subsidiary Sciences of Archaeology, provided technological and scientific services to archaeological and cultural heritage study. Shortly after, in 1981, the unit became the Institute for Technologies Applied to Cultural Heritage (ITABC).

In 1982, the Institute for Phoenician and Punic Civilisation was established in Montelibretti, thanks to the activities of the Study Centre for Phoenician and Punic Civilization (1969).

In Southern Italy, in 1984, the CNR Centre for Greek Archaeology was founded, in Sicily, by Giovanni Rizza at the University of Catania.

During 1988, the Institute for the conservation of monumental works was born in Lecce, and the International Institute of Frederician Studies took shape in Potenza.

In the same year, the Committee for Science and Technology of Cultural Heritage, established by CNR, carried out a significant action of coordination and propulsion for research activities in the field of Cultural Heritage.
