The Split Archaeological Museum is the oldest museum in Croatia when it was established in 1820 by a decree of the Dalmatian government in Zadar. Some 150,000 artifacts cover prehistoric times, the period of Greek colonization of the Adriatic, Roman Provincial and Early Christian era to the early Middle Ages and the period of Croatian popular rulers. There is a collection of stone inscriptions from Salona and the collections of Graeco-Hellenistic ceramic objects, Roman glass, ancient clay lamps, bone, and metal articles, gems and coins. The museum is housed at Zrinsko-Frankopanska 25 in Split. There is also a branch building in Solin (Salona and Tusculum ) and two regional centres at Vid near Metković (Narona Collection), and on the island of Vis. The museum complex consists of a two-story main building with the exhibition halls on the ground floor and the museum library as well as study rooms on the 1st floor as well as a row of arcades surrounding the main building (for the lapidarium ) and an attached garden.
