Stari Grad Museum takes care of thirteen collections, each of which keeps valuable material on the history of Stari Grad and the island of Hvar. Thematically, collections can be divided into four main divisions, namely the archaeological, ethnographic, historical and artistic collections.
Archaeological division consists of four collections: archaeological, hydro-archaeological, numismatics and collection of stone monuments and mosaics.
Archaeological collection consists mostly of items found during the various archaeological excavations in the area of Stari Grad, from the time of prehistoric settlement (6th and 5th century BC), the period of the Greek city of Pharos (4th – 2nd c. BC) to the Roman and later Pharia (1st c. BC – 7th c. AD).
Hydro-archaeological collection consists of the cargo of the late Roman shipwreck found in Duboka bay, on the northern coast of the island, and these are mostly amphorae and fragments of ship equipment.
Numismatics collection consists of several hundred coins found during the archaeological excavations in Stari Grad.
The collection of stone monuments and mosaics mostly consists of items found during archaeological research on the site of Remete vrt (Pharos archaeological site) ie. the part of the site with the remains of the Early Christian twin churches of St John and St Mary.
Ethnographic collection consists of items from everyday island life, as well as items related to the economy, especially the wine and olive oil production. The collection is dislocated in the west wing of Hektorović’s Tvrdalj.
