The site of the ancient city of Cemenelum, capital of the Alpes Maritimae province, following Augustus' conquest of the Alps and the organization of the Ligurian territory, boasts three complete thermal bath complexes, streets, a drainage network, a schola, a domus and some boutiques. Close to the site, in the Garden of the Arenas is the amphitheater indicating the ancient city's northwest boundary. Predominantly from the 3rd century, these vestiges comprise in fact different stages of construction spanning from the 1st to the 7th century. The buildings' technical aspects, namely the heating system, are visible at the thermal complex on the east side. The thermal ensemble on the west side, rebuilt in the late 4th early 5th century, harbors the remains of a paleo-Christian church and baptistry, the last manifestations of urban life in the 5th century. Models of these buildings are on display in the Museum's belvedere, which also offers a view of the site. Inaugurated in January 1989, the museum replaces the site's first museum created in 1960 in the Villa des Arènes, which is now the Matisse Museum. Collections cover the metal ages, and antiquity up to the Early Middle Ages. They deal with life in Cemenelum and the Alpes Maritimae province, through a number of objects and official or personal documents discovered during the archeological excavations conducted between 1950 and 1969 on the site acquired by the Municipality of Nice as well as others.
