Situated 2 km from Murighiol, Halmyris was for over six centuries a Roman legionary base with two gates, 15 towers and a naval port. At the mouth of the Romanian Danube Delta, it was the outpost at the furthest north-eastern point of the Roman Empire. The fort and the base have been excavated. In Roman times this settlement on the shore of Halmyris Gulf (Halmyris means salt water) was known as Salmorus or Thalamonium. Two Getic burial sites found nearby indicate settlements that date back to the 3rd and 2nd centuries BC. The Romans built a stone “castrum” during the reign of Emperor Trajan. The fortress was destroyed several times, underwent four phases of reconstruction and was finally abandoned in the 7th century AD. In the early 4th century, Emperor Constantine the Great constructed a basilica here. Earthquakes altered the Danube course which eventually left the port and Halmyris without any trace of its existence.
