Arheološki Muzej Istre, i.e. the Archaeological Museum of Istria, is a multi-branch facility that presents three permanent exhibitions in the main office: collections of exhibits from prehistoric times, an exhibition of collections from the Roman rule and a collection of exhibits from early medieval castles and churches.
The most valuable monuments of the Roman period in Pula are under the care of the Archaeological Museum of Istria: the Amphitheater, the Temple of Augustus and the ruins of Nesactium - a Roman city built on the ruins of an ancient castle of the Histri tribe. Other museum facilities include a Franciscan monastery and a modern exhibition space at Sacred Hearts (the former church of the Sercarek Sisters).
The beginnings of the Archaeological Museum date back to 1925, when the Royal Istrian Museum was established to secure collections from the Temple of Augustus, Nesactium and archaeological collections from the Regional Museum in Porec. In 1947, the facility was renamed and was renamed the Archaeological Museum of Istria.
