The former Spa thermal baths, designed by Léon Suys, feature eclectic architecture adorned with sculptures and pilasters. The entrance hall, by Joseph Carpay, is decorated with mythological subjects and elements inspired by Antiquity. Two fountains fed by the famous springs of Spa are located in the hall. The layout of the building was designed to meet the thermal needs of the time, with levels dedicated to baths, changing rooms and doctors' surgeries. A project to convert the building into a mixed-use complex is currently underway and is due to be completed in 2024.
