After the interest in Cucuruzzu in 1959 by Roger Grosjean, archaeologist known for having studied Filitosa, and the excavations which he proceeded in 1963 and 1964, the site was acquired in 1975 by state and declared historical monument in 1982. It is now owned by the Territorial Collectivity of Corsica.
Restored in 1991, stripping the vegetation which invaded it, its development provides public access while limiting its degradation.
