Granit Tarn is mined in south-western France, in the department of Tarn (hence its name), in a massif called Sidobre, near Castres. Its remarkable properties, such as very low absorbency and total frost resistance, make it one of the hardest and best granites in the world.
Its visual and aesthetic aspect is also unique because of its nice, gray color and very regular grain size.

French granite Tarn is known all over the world. This is evidenced by numerous facades of buildings, floors and pavements that were made of it, among others:
- Champs Elysees in Paris, France.
- Jean Jaures Square in Castres, France.
- Olympic stadium in Barcelona, Spain.
