Wiesbaden and its sources
Wiesbaden's thermal springs are among the hottest in Europe. Here you can find out interesting facts about the 26 springs, the legend of their origins and where you can relax in the thermal water.
- In Wiesbaden, 26 hot springs bubble up from the earth. With temperatures of up to 67°C, they are among the hottest in Europe. The Kochbrunnen is the hottest spring in the city.
- Every day, around two million liters of thermal water rise to the surface from a depth of around 2,000 meters.
- On its journey from the depths, the water absorbs valuable minerals such as calcium, magnesium, strontium, and iron. While it was formerly used for drinking cures, today it is mainly used for thermal baths.
- The water is very salty – up to six grams of table salt per liter of water. That's around 14 tons of table salt per day!
- The Romans already used Wiesbaden's thermal springs. Between 6 and 16 AD, they founded the settlement "Aquae Mattiacorum" with thermal baths for the recovery of their soldiers. This is commemorated by the inscription on the "Aquis Mattiacis" spa building – dedicated to the waters of the Mattiakers.
- The thermal water is an inexhaustible source of energy and is ideal for heating. Today, around 440,000 cubic meters of thermal water are extracted annually from five springs, generating 16 gigawatt hours of heat (opens in a new tab)heat (opens in a new tab). However, the high salt content makes the thermal water corrosive – contact with oxygen quickly causes limescale to form, which makes it difficult to use.

Fancy some relaxation? This way please!
Kaiser-Friedrich-Therme
The Kaiser Friedrich Thermal Baths are considered the jewel among Wiesbaden's thermal baths. None other than Emperor Wilhelm II, a regular visitor to the city's spas, once complained that Wiesbaden had "the most beautiful spa house in the world" but no public baths befitting its status. As a result, architect August O. Pauly created an Art Nouveau building that draws on the Roman bathing tradition.
The foyer, decorated with stucco and reliefs, gives you an idea of how stylish relaxation can look! The thermal baths are still fed by the Adlerquelle spring today.

Bathhouse in the Hotel Schwarzer Bock
The Hotel Schwarzer Bock is considered Germany's oldest grand hotel. As early as the 15th century, crowned heads, artists, and spa guests from all over Europe sought relief and relaxation here. Today's bathhouse, which can be booked as a day spa, combines the listed spa architecture with a purist-designed spa featuring a thermal pool, sauna, steam bath, and relaxation areas. Incidentally, the thermal water comes from the neighboring Kochbrunnen spring. The highlight: the Kochbrunnen bath (opens in a new tab)!
Thermal bath Aukammtal
The Aukammtal thermal baths have just been renovated. Surrounded by greenery, the baths invite you to relax in mineral-rich thermal water from their own spring. Various saunas (the highlight is the quadro sauna) and steam baths await you in the indoor and outdoor areas, as well as an outdoor pool with a water temperature of around 32°C.
The legendary origin of the springs
In ancient times, when giants and dragons still lived on Earth, the giant Ekko lived in the area that is now Wiesbaden. He felt disturbed by a dragon that lived in the dense forests of the Taunus. Ekko resolutely set out to kill the fire-breathing monster. But despite all his efforts, he was unable to find either the dragon itself or its hiding place.
This futile search made the giant furious. In his rage, he rammed his spear deep into the ground. Then he thought he heard the dragon's mocking laughter coming from the depths. To be sure, Ekko pulled the spear out again. At that moment, boiling hot water shot out of the earth and burned his bare feet. The pain only made him angrier.
Convinced that he had found the dragon's whereabouts, Ekko repeatedly thrust his spear into the ground—each time deeper than before. Suddenly, a powerful jet of hot water hit him directly in the face. He lost his balance and was barely able to catch himself. In doing so, his left hand and forearm sank deep into the softened ground.
Cursing, the giant finally gave up. With his face scalded and his feet swollen, he withdrew. But the marks left by his arm and fingers remained and, according to legend, are still visible today.
This, it is said, is how the valleys, hills, and thermal springs of Wiesbaden came into being. The surface of the hand forms the Wiesbaden basin, while the thumb, fingers, and forearm represent the valleys. And in the places where Ekko thrust his spear into the ground, hot water has been bubbling out of the ground ever since.
Quellgeflüster tip: There is a lovely children's book about the giant Ekko: Wiesbaden, a journey of discovery with the giant Ekko (opens in a new tab). On this journey of discovery, he is accompanied by Marie and Bruno, who find a stack of old books about Wiesbaden in an old suitcase while rummaging around in the attic. As they read, they repeatedly come across the legend of the giant Ekko. Here (opens in a new tab) you can find a video about how the book came to be!
