Komárno, spreading on the eastern tip of Žitný ostrov at the confluence of the Danube and the river Váh, has been continously inhabited since the Late Bronze Age. This location was inhabited by the Celts and later the Romans built a military camp here. At the time of the great migration, the Avars lived in the Komárno territory. During the 10th century, Hungarian tribes built a fortified and fenced place at the confluence of the Danube and the Váh, which later became the centre of the Komárno district.
