Oricum is located to the right of the Vlora-Saranda national road and 42 km south of the Greek colony of Apollonia. According to Pseudo-Scymnos, the city of Oricum was established by Euboeans who, being on their way home from Troy were blown off their route by strong winds. Its geographical position made it an important harbor on the Adriatic coast.
Oricum was used by the Romans in ancient times as a defensive base in the wars against the Illyrians as well as in the 3rd century B.C. against the Macedonians, who in fact occupied it in 214 B.C. Julius Caesar stationed his troops in camps there for several months, until they were taken by Pompey (Pompeius Magnus).
Being in the crossroads of such influences, Oricum became a civilized urban centre, as evidenced by various archaeological ruins, such as part of an Orchestra, a small theatre, which is thought to have seated 400 spectators, traces of wall ruins and streets that are clearly seen, albeit lying under the water of the lagoon, and the nearby Marmiroi Church. This is a church of dating back to the early Byzantine period, of the Byzantine emperor Theodore of the 13th century A.D. It has a small 6m x 9m main hall and a dome approximately 3m in diameter that is supported by four Roman arches.
