A Masterpiece on the Olt River
The dam is part of a complex system of hydroelectric power plants built along the Olt River. What makes this specific location special for tourists is the dramatic backdrop. As you drive along the E81 road (the main route connecting Transylvania and Wallachia), the sight of the massive concrete structure holding back the blue waters of the river, framed by vertical forest-covered cliffs, is breathtaking.
Legend and History at the Foot of the Dam
Just a stone's throw away lies the Cozia Monastery (Mănăstirea Cozia), built by Mircea the Elder in 1388.
- The Legend of the Foundation: It is said that the Prince chose this spot because of a hermit who lived in the hollow of an oak tree, suggesting the land was blessed.
- The Silent Watcher: For centuries, the monks here lived in the quiet of the defile. Today, the modern dam stands as a silent technological guardian next to this medieval masterpiece, creating a unique contrast between the 14th and 20th centuries.

The dam is the entry point to the Cozia National Park, a protected area famous for:
- Thermal Springs: The region is renowned for its healing waters, fueling the nearby resorts of Călimănești and Căciulata.
- The "Edelweiss" of the Valley: If you hike up from the dam towards the Cozia Ridge, you can find rare alpine flowers and, if you are lucky, the majestic golden eagle soaring above the Olt.
- The Sinking History: When the dam was built and the reservoir filled, some parts of the old Roman road (Via Traiana) and historical sites were submerged forever, preserved now only in old maps and deep under the waters of the Olt.
- A Photographer’s Dream: The best time to visit is at dawn, when the mist rises from the reservoir, partially hiding the dam and giving the entire valley a mystical, "Lord of the Rings" vibe.
- Roman Heritage: Right next to the dam area, you can visit Castra Traiana, the ruins of an ancient Roman fort that once guarded this vital passage through the mountains.
