The original building is structurally cracked and sinking - the collection is temporarily relocated, showing only a fraction of 8,000+ artifacts. A new permanent museum isn't expected before 2029.
The museum originated as an Archaeology Museum unit under Goa's Department of Archives in 1973, opening to the public in a rented building on 29 September 1977. A dedicated museum complex at Patto Plaza in Panaji was formally inaugurated by India's President on 18 June 1996, before the entire collection was relocated again to the historic Old Secretariat (Idalcao Palace) building in June 2017. Its roughly 8,000 artifacts span stone sculptures, bronzes, Christian art, Hindu temple carvings, and manuscripts, offering a rare single-site overview of Goa's pre-Portuguese and colonial-era history.
