Devín Castle by Danube boat — the cliff-top ruin where the Morava meets the Danube
Sail upstream from the Old Town quay to the dramatic ruined fortress of Devín, perched on a crag at the confluence of the Danube and Morava rivers, with Austria on the far bank. This was a frontier stronghold of Great Moravia, blown up by Napoleon's troops in 1809, and later a symbolic point on the Iron Curtain — the river below was a Cold War kill-zone. Arriving by water, watching the castle rise from the cliff, is one of the great approaches in Central Europe.
