The Cemenelum ruins occupy the Cimiez hill, a residential district north of central Nice in the Provence-Alpes-Côte d'Azur region of France, beside the Avenue des Arènes de Cimiez. In the early Roman Empire the town was founded as a military and administrative post and became the capital of the province of Alpes Maritimae, governed by a procurator.

The Cemenelum ruins occupy the Cimiez hill, a residential district north of central Nice in the Provence-Alpes-Côte d'Azur region of France, beside the Avenue des Arènes de Cimiez. In the early Roman Empire the town was founded as a military and administrative post and became the capital of the province of Alpes Maritimae, governed by a procurator. It stood on a plateau above the coastal port of Nikaia, which was then a smaller Greek-origin settlement, and reached its height in the 2nd and 3rd centuries CE before declining as the population drifted toward the coast in late antiquity. The visible archaeological zone centres on three public bathing complexes, laid out on a monumental scale and identified by their hot, warm and cold rooms, heating systems, drains and mosaic fragments. The northern baths, the eastern baths and the western baths together show how bathing, exercise and social life structured a provincial Roman town. Nearby lie the small amphitheatre, which could hold several thousand spectators and now hosts summer concerts, and traces of streets and a paleochristian church and baptistery from the later phase of occupation. The remains are low walls and foundations rather than standing buildings, set among olive trees and lawns, so the experience is that of an open-air excavation read through labels and the finds displayed in the adjacent archaeology museum. Excavations began in the 19th century and continued through the 20th, and the site is maintained by the City of Nice, with periodic consolidation of the masonry and protection of the more fragile floors. Visitors typically combine the ruins with the Matisse museum, which stands next door, and with the Cimiez monastery gardens a short walk away. The grounds are free, and a full visit including the museum takes about one to two hours. Paths are gravelled and uneven in places and there are slopes between the baths and the amphitheatre, so comfortable shoes help. Opening times vary by season and the phone number listed for the museum can confirm the current schedule before travelling.
