Umag was mentioned for the first time in the 7th century by an anonymous citizen from Ravenna, but had already existed in Roman times. Proof of that is found in the numerous remains of Roman retreats, the so-called villa rustica uncovered all along the coast. The town's history is closely linked to the settlement of Sipar whose ruins can be found on the narrow cape, six kilometres north of Umag.
