By collecting stone monuments in the Temple of Augustus in 1802, marshal Marmont began the founding of the museum collection in Pula. However, the discovery of stone, ceramic and metal objects in Nesactium was the basis for founding the Museo Civico (City Museum) in Pula in 1902. After the seat of the “Società istriana di archeologia e storia patria” had been moved and with the transfer of the archaeological inventory from Poreč to Pula, the Museo Civico was integrated with the National collection (stone monuments) and the Poreč Regional Museum (Museo Provinciale) into one regional institution. Therefore, in 1925 the Museum of Istria (Il Regio Museo dell’Istria) was founded in the present-day museum building. In 1930 the museum opened its doors to visitors, and a guidebook in Italian was published. This exhibition, along with minor changes, was open for the public until the end of World War II, when many objects were transferred to Italy during the Anglo-American administration.
