This hamlet developed at the end of the 18th and 19th centuries because of the cattle fairs which took place several times a year.
The biggest village of the district was Saint Georges de Lévéjac, that only changed in 1912, when the priest, Sir Casimir Privat, decided to build a new church in Le Massegros. The church was consecrated in 1914.
The main source of income is the raising of milk ewes. Le Massegros’ diary industry hires 200 persons and it is one of the largest in the world.
Typical old stone houses stand in the core of the village and the most famous one is called "La maison aragonaise". This style shows a covered terrace where the arches and balusters are in harmony with the row of eight little roofs.
You can also discover an 19th century stone baker’s oven, which is a living symbol of the past. Every year, there is a festival and the bread is baked in the old tradition.
When walking in Le Massegros, you will notice the harmony between the old and the new part of the village.

The name must come from the 18th century vineyards on the sunny terrace cultivation of the valley. It is located at the broadening part of the valley and is well sunlit. From Les Vignes, the Gorges of the Tarn’s narrow path is nearly straight and shows a nearly perfect symmetry from the steep river banks covered by forests and surmounted by opposite calcareous chaos which form the two Causses mountains : The Sauveterre Causse and the Méjean Causse.

In times past, pine logs were thrown down from the Méjean Causse to Les Vignes ; from where they were shipped to the potter’s kiln or to harbours to build ships.
Opposite, on the Sauveterre Causse, there was the "millstone ravine", where heavy stones were transferred . The Dolan and Blanquefort castles (now in ruins) located on each side of the valley were there to protect major routes linked to the river.
