The Gaul era: Nériomagos

At that time, Néris was called Nériomagos (the town of Nérios, the deity personifying the thermal spring). It was a village with a booming trade, at the crossroads of two major ways.

The Roman colonisation: Aquae Nerii

"Nérios" was Latinized into "Nérius", and "Nériomagos" became "Aquae Nerii" ("Nérius' waters"). The spring was used for therapeutic purposes and two luxurious thermal baths were created. Numerous monuments were built, including temples and villas. The 8th legion Augusta stationed there at the end of the 1st century. A circle theater (amphitheater) was built to offer circus games and stage performances to the soldiers and inhabitants. Many relics remain from that golden age.

Germanic invasions and Merovingian era

Around 275 C.E., the Germanic invasions destroyed a part of the town and the population fled, leaving behind monetary treasures.

In the 4th century, the thermal baths and the houses were partly rearranged and occupied again.

A new wave of invasions destroyed the town again, and the ruins were then used as a gravel-pit by the Merovingian population. Stone blocks belonging to the public buildings were thus used for the sarcophaguses now located under the glass pyramid on the church square.

Evangelism and Carolingian era

Saint Patrocle evangelized Néris in the 6th century and built a church and a convent there. The current romanesque church dates back to the 11th or 12th century and was built in the same place as the original 6th-century basilica, which was erected upon the ruins of a Roman building.

The Carolingian king Pépin the First of Aquitaine, Charlemagne's grandson, stayed in Néris in 835 and 838.

The 16th century

Néris' thermal baths' fame increased. Rabelais mentioned them in Pantagruel (which is why Néris' middle school is called Collège François Rabelais), and Nicolas de Nicolay, King Charles the Ninth of France' geographer, cited the "Baings de Nérys" in 1569 (modern orthograph: Bains de Néris = Baths of Néris).

The 19th century

Néris' new golden age began when the Dauphine, Duchess of Angoulême, lay the foundation stone of the new thermal resort. The hotels, the casino and the theater were built.

Among the famous people who followed a thermal course of treatment in Néri were Chateaubriand, Musset, Lamartine and the empress Eugénie.

At that time, archaeological excavations began to discover the Roman Aquae Nerii's infrastructure.

Society life was in full swing, and grand parties were organized.

The 20th century

Néris became a "hospital town" during the first World War, where injured soldiers were taken care of.

By the end of the war, the thermal baths were prosperous again. In 1930, the railroad line between Néris and Montluçon entered service, as did the train station in Néris, with its pink sandstone and its multicolored roof, designed by Louis Brachet. The bourgeoisie and the politic class used the thermal baths, including the Poincaré family, and Léon Blum.

The second World War and the social progress that preceded it (Social Security and paid vacation) gave the town a new look and a new clientele.

The thermal baths were modernized and the town equipped itself with golf, an archaeological museum and a swimming pool. Néris started opening up to health tourism and emphasizing its heritage.
