This thermal bath is the perfect place for some much needed R&R after exploring the city. Purge yourself of toxins in the steam rooms, inhale the scent of essential oils in the sauna, or simply unwind in the warmth of the tepidarium. The Kaiser-Friedrich- Therme has maintained its original Irish- Roman appeal throughout the rooms. The historic swimming hall is the beating heart, and the saunas still have intricate frescoes and ceramics from the late Jugendstil period. The thermal baths here were first discovered by the Romans some 2000 years ago, and to this day, Wiesbaden is one of the most famous wellness destinations in the world. Even the poet Goethe wrote how healing he found the baths to be in letters to his wife.
