Upper floor The upper floor was designed for bathers and therapeutic visitors, with the symmetrical layout of imperial double baths, with duplicated
palaestrae, gymnasiums,
frigidaria, and heated rooms, following a central-to-peripheral path. Outside, two pools and two
palaestrae served as solariums, one for each circuit.
Materials and decoration Pool floors were made of limestone or marble, with many rooms having wooden flooring. The construction used limestone and
impactite stones, the latter formed by a meteorite impact creating the Rochechouart-Chassenon crater. These impactites, varied in color and texture, are resistant to temperature and frost and were quarried south of Longeas. Limestone slabs for wall and floor coverings came from Charente, while granite was sourced from
