Herculane spa and the healing waters in the Carpathians
The rich history of Romania’s oldest spa

Nestled in the canyon of the Cerna river, near the border with Serbia, Herculane spa is the oldest and most renowned health resort in Romania. Its thermal springs have attracted visitors for thousands of years, while its rich history and unique architecture make it a must-visit destination for tourists from all over the world.
A source of health and the legend of Hercules
This spa owes its name to the ancient Greek hero Hercules. According to legend, it was here that he gained his superhuman strength after defeating the Hydra – a ferocious beast that had been terrorizing the region. The thermal waters, once used by the Dacians and Romans, are still famous today for their healing properties.
The first written records of Herculane date back to 153 AD, during the reign of the Roman emperor Marcus Aurelius. He found rejuvenation in these waters. However, the spa truly flourished in the 18th century, becoming an elite retreat for the aristocracy of the Habsburg monarchy.

Architecture and historical significance
During the Austrian rule, Herculane was built in a distinctive Baroque style, which still dominates its landscape today. Royal figures such as Maria Theresa, emperor Franz Joseph, and his wife empress Sisi were regular visitors to this health resort. Serbian king Alexander Obrenović and Romanian king Carol I also stayed at the spa, enjoying its healing waters and luxurious pavilions.
Today, remnants of the Roman baths in Herculane have been preserved and are still in use. One of the most famous attractions is the Hercules Saltwater Spring, known for its mineral composition that resembles seawater.
Healing springs and beneficial climate
Herculane spa has a total of 19 thermal springs, some reaching temperatures of up to 62 degrees Celsius. Their composition, rich in sulfur, iodine, calcium, and bromine, makes them suitable for treating various health conditions, including rheumatic diseases, skin problems, and respiratory disorders.
Besides its thermal waters, the spa is known for its air, which is exceptionally rich in negative ions. They are over 2,000 per cubic centimeter — similar to areas at altitudes above 2,000 meters. This natural characteristic helps reduce stress and improve overall health.
Herculane spa today
Today, Herculane attracts numerous tourists from around the world, seeking both healing and its unique historical and architectural heritage. The Domogled National Park, which surrounds the spa, offers additional opportunities for hiking and exploring nature.
The preserved Roman baths, Austro-Hungarian pavilions, and rich natural surroundings make Herculane spa not just a place for relaxation but also a destination where history and nature create a unique harmony.
