Gabčíkovo–Nagymaros Waterworks

The Gabčíkovo-Nagymaros Waterworks is a dam system on the Danube between Hungary and Slovakia. It combines a reservoir, main dam structure, and power station spread across the river valley.

The project started in 1977 through an agreement between Czechoslovakia and Hungary. Hungary withdrew later due to concerns about environmental damage and financial costs.

The project represents a shared approach to managing a major European river between two nations. It shapes how both countries think about using water resources and generating power today.

You can view the complex from both riverbanks with observation points and walking paths offering different perspectives. The area is best visited outside of flood season when water levels are more stable.

The International Court of Justice settled disputes between Hungary and Slovakia over this project. This made it a landmark case in how countries resolve water-sharing disagreements.
