Maison natale de Jean Jaurès, Birth house of political leader in Castres, France.

The Maison natale de Jean Jaurès is a three-storey house in greyish-beige render with a steep tiled roof, its windows fitted with pale blue wooden shutters, most in pairs and some closed. An arched doorway with a blue door, numbered 8, sits near the lower left of the facade, with a grey downpipe and a red pipe running down the right edge. The second floor is a granary open to the garden and filled with weaver's equipment, the original trade of the Jaurès family in Castres.

Built in the 19th century, the house belonged to the Barbaza family, that of Jaurès's mother Adélaïde Barbaza. Jaurès was born there on 3 September 1859, most likely in one of the ground-floor rooms. He then spent his childhood at the Fédial estate. The house was listed as a monument historique on 28 December 1984, and its facade was renovated with a new plaque added in 2025.

The attic, open to the garden, is filled with weaving equipment, a reminder that the Jaurès family's original trade in Castres was weaving. The house thus ties the birth of the politician to a family craft rather than to a grand estate.

The house is a private residence and cannot be visited inside; the facade, with its blue shutters and the door numbered 8, is seen from the street. It was listed as a monument historique on 28 December 1984, and its facade was renovated with a new plaque added in 2025.

The facade was renovated and a new plaque added in 2025, replacing or supplementing the earlier marker. The house itself is a typical Castres building of its era, with a steep tiled roof and pale blue wooden shutters, and the attic above still holds weavers' equipment from the Jaurès family's original trade in Castres.
