History of Aachen Thermal Baths

First, let’s start with some history. The thermal springs in Aachen were discovered by the Romans over 2,000 years ago, and since then, they have been used for their healing properties. The Carolus Thermen, named after Emperor Charlemagne, who was a frequent visitor to the thermal springs, was opened in 2001 as a modern thermal bath complex, but still preserves the historic atmosphere of the original Roman baths.

In Aachen, water and wellness have a long tradition. While in former times, the Romans relaxed in the therapeutic waters of the Aachen mineral springs, today, the Aachen Thermal Baths (Carolus Thermen) offer the perfect escape from everyday life.

The complex covers an area of 11,000 square meters and features a variety of indoor and outdoor pools with temperatures ranging from 28°C to 38°C, as well as saunas, steam rooms, and relaxation areas. The pools are filled with water from the thermal springs, which is said to have a positive effect on the body, reducing stress and promoting relaxation. The Carolus Thermen continuously receive fresh mineral thermal water of the best quality via a pipeline from the Aachen Rose Spring. The spring is located – covered by buildings, but perfectly protected – in the middle of Aachen’s city center, in Komphausbadstraße. At the spring directly, the temperature of the water averages 47°C.  The outdoor pools offer a beautiful view of the surrounding park and are perfect for enjoying the fresh air while soaking in the warm water.

In addition to the pools, the Carolus Thermen also offers a range of spa treatments, including massages, facials, and body wraps. These treatments are designed to promote relaxation, relieve stress, and rejuvenate the body and mind. The spa treatments are performed by trained professionals in a peaceful and serene environment, adding to the overall relaxing experience.

The Carolus Thermen also features a restaurant, which offers a variety of healthy and delicious meals and drinks. The restaurant has a beautiful terrace overlooking the park and is the perfect place to enjoy a meal or a drink after a relaxing day at the thermal bath.
