Tartonne (French pronunciation: [taʁtɔn]; Occitan: Tartona) is a commune in the Alpes-de-Haute-Provence department in southeastern France.

The landscape is marked by robine [fr], a sedimentary rock of black color which is very soft and crumbly to air, but which is very strong in the subsoil.

The habitat is very dispersed, and one can distinguish five groups of hamlets which are very distant from each other (up to 10 km): This distance is due to the poverty of the soil, and the difficulty of building: the strong gradients, the presence of numerous watercourses, and the instability of the land, means that more than 85% of the territory of the commune is unbuildable.

[12] Negre is disputed by Raymond Sindou, who considers unlikely a lack of change of the name for 1,500 years, and offers a comparison, without a sense of moving forward, Tortona to Dertosa in Hispania Tarraconensis and Dertona in Cisalpine Gaul.

[13] The name of the Summit of Cucuyon at 1,886 metres (6,188 ft), is formed on the pre-Celtic root *Kug-, another oronym, with repetition and addition of a diminutive suffix.

[14] The first traces of occupation date back to the Gallo-Roman at the current location of the hamlet of Petit Defend.

It is difficult to know the name of the Gallic tribe that inhabited the valley, and the name of the civitas which Tartonne depended on in the early Empire: Eturamina (Thorame) or Sanitensium (Senez).

At the end of the Roman Empire, the connection to that of Sanitensium, and its diocese, was proved with the disappearance of the bishopric of Thorame.

[21] The Revolution and the Empire brought many improvements, including a land value tax equal to all, and proportional to the value of the assets of each.

The Finance Act [fr] on 15 September 1807 specified its terms, but its realisation took a long time to implement, officials of the cadastre dealing with the communes in successive geographical groups.

In the area, many airdrops of weapons and the establishment of STO (which led many young people to come to the vicinity) allowed the resistance to carry out actions against the German army, which occupied the region from 1942.

[36][37] Other works have been carried out by an association for the safeguarding of the building, including to the floor, roof, wall, and sundial.
