Glanum (Hellenistic Γλανόν, as well as Glano, Calum, Clano, Clanum, Glanu, Glano) was an ancient and wealthy city which still enjoys a magnificent setting below a gorge on the flanks of the Alpilles mountains. It is located about one kilometre south of the town of Saint-Rémy-de-Provence. Originally a Celto-Ligurian oppidum, it expanded under Greek influence before becoming a Roman city. As it was never built over by settlements after the Roman period but was partly buried by deposits washed from the hills above, much of it was preserved. Many of the impressive buildings have been excavated and can be visited today. It is particularly known for two well-preserved Roman monuments of the 1st century BC, known as "Les Antiques", a mausoleum and a triumphal arch. Between the 4th and 2nd centuries BC, the Salyens, the largest of the Celto-Ligurian tribes in Provence, built a rampart of stones on the peaks that surrounded the valley of Notre-Dame-de-Laval, and constructed an oppidum, or fortified town, around the spring in the valley, which was known for its healing powers. A shrine was built at the spring to Glanis, a Celtic god. The town grew, and a second wall was built in the 2nd century BC. The town had a strong Celtic identity, shown by the names of the residents (Vrittakos, Eporix, Litumaros); by the names of the local gods (Glanis and his companions, the Glanicae, (similar to the Roman Matres); and the goddesses Rosmerta and Epona); by the statues and pottery; by the customs, such as displaying the severed heads of enemies at the city gate; and by the cooking utensils found in the ruins, which showed that the people of Glanis boiled their food in pots, rather than frying it in pans like other Mediterranean tribes. The people of Glanum were in early contact with the Greek colony of Massalia, present day Marseille, which had been founded in about 600 BC. The contact influenced the architecture and art of Glanum – villas were built in the Hellenic style.
