Iron Gates Dam (Barajul Portile de Fier): Where the Danube Tames the Mountains and History + video and views
Posted: Fri Jan 23, 2026 4:48 pm
Have you ever wondered what it looks like when the raw power of nature meets the peak of human engineering? The Iron Gates I Hydroelectric & Navigation System is more than just a dam—it is a living legend standing tall on the border between Romania and Serbia.
Why the Iron Gates Should Be on Your Bucket List
-Completed in 1972 after nearly a decade of monumental effort, this concrete giant literally changed the course of history. Here is why this destination is a must-see:
-An Engineering Marvel: It is the largest dam on the Danube and one of the most powerful hydroelectric plants in Europe. It "disciplines" the river's flow to generate massive amounts of clean energy.
-Breathtaking Landscapes: The dam serves as the gateway to the Danube Gorges (Click HERE to see more) (Djerdap). Here, the river narrows significantly, flanked by towering cliffs that create some of the most dramatic scenery in all of Europe.
-A Glimpse into the Past: At the Iron Gates Museum, you can tour the turbine halls and learn the poignant story of Ada Kaleh—the "Atlantis of the Danube"—a Turkish island submerged forever by the dam's rising waters.
Did You Know?
The construction of the dam raised the water level by approximately 35 meters, creating a reservoir that stretches back 150 km. This project made the Danube navigable for large ships, bypassing the treacherous rocks and whirlpools that once made this stretch of water a sailor's nightmare.
Plan Your Visit
If you want to feel the vibration of the massive turbines beneath your feet and admire the Danube from a unique vantage point, make Drobeta-Turnu Severin your base. From there, you can easily explore the dam, the "Boiling Caulkins" (Cazanele Dunării), and the famous rock sculpture of Decebalus.
Pro Tip: Visit at sunset! The reflection of the orange sky on the vast, still waters of the reservoir is a photographer’s dream.
Geographic Overview: The Iron Gates
-The Iron Gates (Porțile de Fier) represents one of Europe’s most dramatic natural landscapes, serving as a natural border between southwestern Romania and northeastern Serbia.
-Location: It is situated on the lower course of the Danube River, cutting through the Carpathian Mountains to the north and the Balkan Mountains to the south.
-The Gorge: It is one of the largest river gorges in Europe, stretching approximately 134 km (83 miles) from Baziaș to Drobeta-Turnu Severin.
-The Narrowest Point: Known as the Great Cauldrons (Cazanele Mari), the river shrinks to a width of only 150 meters, while the water depth reaches record levels of up to 75–80 meters.
-The Reservoir: The Iron Gates I Dam created a massive reservoir with a volume of over 2.1 billion cubic meters, extending 150 km upstream.
-Protected Areas: The region is home to two major national parks: Iron Gates Natural Park (Romania) and Đerdap National Park (Serbia), preserving unique sub-Mediterranean flora and fauna.

The "Underwater" Monastery Mraconia (Manastirea Mrconia): A Must-See Landmark
No visit to the Iron Gates is complete without witnessing the serene beauty of Mraconia Monastery. Perched dramatically on the river’s edge in the "Small Cauldrons" area, it is often called the "Monastery under water."
A Resilient History: The original 15th-century church was sacrificed and submerged during the construction of the Iron Gates I dam. For decades, it remained a hidden ghost beneath the waves.
A Modern Phoenix: The monastery you see today was rebuilt after 1989, standing as a symbol of endurance. When the Danube’s water level drops significantly, the star-shaped ruins of the old structure can still be glimpsed beneath the surface.
The View: Located just a stone’s throw away from the colossal Rock Sculpture of Decebalus, it offers one of the most photographed views in Eastern Europe—where steep cliffs meet the turquoise waters of the Danube.

Frequently Asked Questions: The Iron Gates I Dam & Museum
1. What is the Iron Gates I Hydroelectric Power Station?
The Iron Gates I (Portile de Fier I) is the largest hydropower plant on the Danube River and one of the largest in Europe. Completed in 1972 as a joint project between Romania and Yugoslavia (now Serbia), the dam stands 60 meters high and stretches nearly 1.3 kilometers across the river.
2. Can tourists visit the interior of the dam?
Yes! There is a dedicated Museum of the Iron Gates Hydroelectric Region located on the Romanian side (near Drobeta-Turnu Severin). Visitors can see:
The massive turbine hall (Kaplan turbines).
Models of the dam's construction.
Ethnographic exhibits from the submerged island of Ada Kaleh.
3. Is there a border crossing at the dam?
Yes. The Iron Gates I Dam serves as a Border Checkpoint (Vama) between Romania and Serbia. It is one of the main crossing points for cars and pedestrians in the region, connecting the Romanian city of Drobeta-Turnu Severin with the Serbian town of Kladovo.
4. How do ships pass through the dam?
Since the dam blocks the natural flow of the river, a system of navigation locks (ecluze) was built on both the Romanian and Serbian banks. Watching a massive cruise ship or cargo barge being lowered or raised within the lock chambers is one of the most impressive sights at the dam.
5. What happened to the island of Ada Kaleh?
Ada Kaleh was a small, inhabited island known for its Turkish heritage, famous for its roses, figs, and Turkish delight. Unfortunately, when the dam was built, the rising water levels of the reservoir completely submerged the island. Most of its historical structures were destroyed, though some were moved to the nearby Șimian Island.
6. Where is the best viewpoint for the dam?
The best views from the Romanian side are from the road (DN6) as you approach from Drobeta-Turnu Severin. For a panoramic perspective, you can also hike in the Iron Gates Natural Park (e.g., Ciucaru Mare), though the dam itself is located a bit further downstream from the narrowest part of the Gorges.
7. What are the visiting hours for the Museum?
The museum is generally open from Tuesday to Sunday (09:00 – 17:00). It is closed on Mondays. However, because it is a high-security facility, it is always best to check for any temporary restrictions or to have your ID/Passport ready.
