Montagne de Lure, Limestone mountain in Alpes-de-Haute-Provence, France.

Montagne de Lure is a 42-kilometre limestone ridge in the Alpes-de-Haute-Provence, peaking at the Signal de Lure at 1,825 metres. Its south face is bare pale limestone cut by gullies, while the north face is marl covered with forest. A road from Saint-Étienne-les-Orgues climbs past the chapel of Notre-Dame-de-Lure, a remnant of a 12th-century abbey.

Human presence on the mountain begins in the Neolithic and continues at the chastelard de Lardiers, a cult and pilgrimage site nicknamed the Lourdes of the Gauls. Roman settlement stayed sporadic, limited to the most fertile sites, and the 13th and 14th centuries saw villages abandoned en masse through war and lack of water. In 1851 the inhabitants, fervent republicans, resisted the coup d'état and were heavily repressed; from 1943 René Char, head of the FFI action-parachutage service, set up Allied weapons drop zones here.

The mountain's name appears in Provençal as Montanha de Lura (classical) and Mountagno de Luro (Mistralian norm). In the Middle Ages it was often called after the patron saints of Sisteron cathedral: montagne de Sainte-Marie, de Saint-Thyrse and de Saint-Marius. The novelist Jean Giono, born and died in Alpes-de-Haute-Provence, first climbed it at eleven on a mule and wrote of it in his first book, Colline (1929).

The ski station has closed for lack of snow, so winter visitors now use the slopes for ski touring and Nordic skiing. A road climbs from Saint-Étienne-les-Orgues to the ridge past the chapel of Notre-Dame-de-Lure, a remnant of a 12th-century abbey. From the tourism office there, cyclists can borrow equipment to time themselves on the climb.

The summit ridge carries a red-and-white striped mast and several thin white masts, visible on the skyline. The ski station below closed for lack of snow and its site now serves ski touring and Nordic skiing. The road climb from Saint-Étienne-les-Orgues measures 17.7 km at 5.7%.
