Ratiaria

Ratiaria (or: Ratsaria, Raetiaria, Retiaria, Reciaria, Razaria; Bulgarian: Рациария; Greek: Ραζαρία μητρόπολις;) was a city founded by the Moesians, a Daco-Thracian tribe, in the 4th century BC, along the river Danube. In Roman times it was named Colonia Ulpia Traiana Ratiaria. It is located 2 km west of the present village of Archar in Vidin Province, northwestern Bulgaria and 3 km east of the present Balta Neagră Natural Reserve in southern Romania. The closest modern cities are Vidin (27 km to the north west), Lom (28 km to the east) in Bulgaria and Calafat (41 km to the north) in Romania. An archaeological museum for the site has recently been established in Dimovo.
