Devín Castle (Slovak: hrad Devín or Devínsky hrad, Hungarian: Dévényi vár, German: Burg Theben) is a castle in Devín, which is a borough of Bratislava, the capital of Slovakia. Owing to its strategic position, the cliff (altitude of 212 meters) at the confluence of the Danube and Morava rivers was an ideal place for a fort. Its owner could control the important trade route along the Danube as well as one branch of the Amber Road. That is why the site has been settled since the Neolithic and fortified since the Bronze and Iron Age. Later, both the Celts and the Romans built strong fortresses there. In the Roman ruins, the first Christian church located North of the Danube has been identified.
