Devín (Hungarian: Dévény, German: Theben) originally a separate town at the confluence of the Danube and Morava rivers, is now a suburb of Bratislava, the capital of Slovakia. It is an important archaeological site, famous for the ruins of Devín Castle. Devín lies near the Devín Gate, which was viewed as the western gateway to the Kingdom of Hungary

It lies on the border between Slovakia and Austria which runs down the middle of the Morava and Danube rivers, and which previously formed part of the Iron Curtain between East and West.

The name stems from the Slovak word deva, which signifies "girl".

Thanks to its strategic location at the confluence of the rivers Danube and Morava, the nearby cliff was an ideal place for a fort. The site has been settled since the Neolithic and both the Celts and Romans built forts here.

Devín was first mentioned in a document from 1237 under the name Villa Thebyn. Originally, it was a small village, belonging to the Devín Castle, but quickly attained the status of a small town in the 15th century. In 1568, Devín became separated from its former owner. Croats fleeing from the approaching Ottomans in the south settled here in the 16th century. The castle above the village was burned down by Napoleon's troops in 1809. From October 1938 to April 1945, Devín was part of the German Third Reich, being part of the Lower Austria. In 1946, Devín was returned to Czechoslovakia and became part of Bratislava.
