The ancient agglomeration named Cassinomagus (current village of Chassenon) was located in the province of Aquitaine and belonged to the city of Lémovices whose chief town was the ancient Limoges: Augustoritum .

Cassinomagus was on the way to Agrippa which crossed Roman Gaul from Saintes to Lyon, from the 1st century AD.

It was in the 1st century BC that Julius Caesar transformed Gaul into Roman provinces. Buildings emblematic of the adoption of a new art of living were then built. Imagine that almost 2000 years ago stood in Chassenon a monumental complex composed of public and religious buildings. Locals and travelers alike could find here a theater (still buried under the vegetation), a temple 30 meters high today destroyed, as well as thermal baths: the best preserved vestiges of France.


The thermal baths were built at the beginning of the 2nd century AD on a double plan, according to the imperial model prevalent in Rome. Less gigantic and luxurious than the Roman examples, the thermal baths of Cassinomagus still have an area of ​​10,000 m².

The thermal baths are one of the major buildings of the Roman way of life. They are used for hygiene, beauty care and physical exercise. But it is also a place of meeting and exchange. All social classes combined, the population finds itself at the edge of the pools, in treatment rooms, under porticoes, in gardens…. Different times or days are probably offered to men and women accompanied by their children.

The use of thermal baths is based on a principle of progressive heating of the body to end in brutal cooling. Beforehand, the body is coated with oil in order to cause, by perspiration due to the heating of the body, a saponification which cleanses the epidermis; the route therefore begins either with physical exercise in the dedicated rooms (gymnasiums or palestres), or with perspiration and immersion in the hot baths of the hot rooms ( caldarium , hot pools). The user goes through the warm rooms ( tepidarium ), a transitional space to get the body used to temperature variations. The bath ritual ends in cold rooms ( frigidaria ) or in outdoor spaces (palatial natatio ) to restore tone and firm up the skin. The body treatment rooms ( unctoria - destrictaria ) allowed users to thoroughly cleanse their skin using the strigile, or to be massaged, depilated, shaved ...

The water was brought, cold, by an aqueduct which also supplied the temple. Cold water was distributed either in the cold basins and fountains or in boilers allowing it to be heated and then supplied to the hot basins.

Twelve ovens were used to heat the water but also all the hot rooms thanks to the ingenious hypocaust heating.

We now know that the building functioned for more than 150 years, before being partially destroyed by a fire at the end of the third century AD.

With the progressive abandonment of the thermal baths, nature resumed its rights. And the burial of the remains favored the exceptional conservation of the building, allowing us today to better understand its construction and use of the time.


The sanctuary would have been built at the end of the 1st century - beginning of the 2nd century AD. AD and is today estimated at 7 hectares including a temple 30 meters high and a sacred wood, one of the largest places of worship in Roman Gaul.

The temple called "de Montélu" would have been built at the end of the 1st century - beginning of the 2nd century AD. AD
Constituted by a podium three meters high, it has a width of forty-seven meters and had an estimated height of thirty meters. It overlooks the thermal baths, the aqueduct and the spectacle building of the monumental complex. Its plan is characteristic of religious architecture in Roman Gaul: a central room, the cella, surrounded by a colonnaded gallery. Here, the cella took the form of a tower of eighteen meters in diameter, octagonal on the outside and circular on the inside.

No deity could be associated with the temple, but archaeological excavations have brought to light arrangements around a recurring theme: water.

The temple is part of a dedicated space made up of two vast esplanades, to the west and to the east. These cultural areas are delimited by a surrounding wall lined by a colonnade gallery, inside (allowing the movement of people).

Near the temple, circles three meters in diameter draw a checkerboard of fifty meters on the side in the natural meadow: they are the imprints of forty-nine pits dug out of the natural rock.

Thanks to archeology and specialized earth sciences, it is now known that these pits were used to accommodate trees or shrubs, thus forming an orderly wood entirely created by human hands. Present within the place of worship, archaeologists identify it with a sacred wood in connection with the divinity.

Unfortunately, analyzes of the pits did not identify the type of trees planted in the sacred wood of the place of worship of Cassinomagus .


It was in the 16th century that Cassinomagus was identified for the first time as an ancient agglomeration. It was then necessary to wait until the 18th century for the first investigations to be carried out there. The research then concentrated on the great temple.

It was finally in the 20th century, in 1958, that the excavations of Jean-Henri Moreau, founder of the Société des Amis de Chassenon, made it possible to identify the remains as thermal baths. He will also search the temple.

Since 1995, professional excavations have made it possible to better understand the architecture and the functioning of this monumental space as well as the thermal baths, the place of worship or even the aqueduct.
