The objects of this collection tell of the Roman presence on the eastern coast of the Adriatic and on the whole derive from the ager of ancient Epidaurus, agrarian colony founded during the reign of Augustus, today Cavtat.

The objects were collected over the years by donations, by field surveys, archaeological excavations and purchases.

The most numerous are potsherds from vessels and amphorae, then fragments of stone architectural decoration and funerary monuments, with a smaller number of objects of glass, metal and bone.

As for stone monuments, particularly prominent are grave stelae, a sculpture of Minerva, the head of a satyr, the head of a bearded man (an emperor), Early Christian capitals and a mensa.

Two recently purchased marble heads show features of the art of portraiture of the Antonines. The first is an excellent portrait of a middle-aged man, more than life size, and the portrait of a youth who once bore a solar crown, sign of his insignia as ruler. The head of a satyr with human and caprine features is somewhat younger. Small pottery, glass, metal and bone objects are witnesses to everyday, spiritual and eschatological life.

The museum has investigated the most important utility remains of Epidaurus, the aqueduct from Vodovađe to Cavtat, the building of which is suggested to have taken place when Publius Cornelius Dollabela (from AD 14 to 20) was governor of Dalmatia, during the reigns of Augustus and Tiberius. One of two incomplete inscriptions from Cavtat, which mention him, tell of the major architectural activity carried out by the 6th cohort. On the Sustjepan peninsula in Cavtat, research has revealed the foundations of ancient city building.
