Specializing in religious sculpture, Louis Castex was particularly active in the Lyon region, where he participated, like many of his colleagues, in the construction of the eight lateral chapels of the nave of the Basilica of Notre-Dame de Fourvière between 1899 and 1943. He executed the altarpiece of "The Annunciation" in 1922, initially entrusted to Jean-Baptiste Larrivé.
In collaboration with goldsmith Amédée Cateland, he created several works dedicated to the Curé of Ars for the Basilica of Saint Philomena in Ars-sur-Formans, Ain.

Castex was also the author of numerous portraits and genre scenes, in relief or in the round. These depictions of characters reading or engaged in fieldwork are mainly distributed between the Musée des Beaux-Arts de Lyon and the Musée départemental de l'Oise in Beauvais.
The presence of Louis Castex's works in these two museums owes much to the active promotion of his work by his children Raoul, Marie-Hélène, and Jean-Marie, who made several donations: in 1990 and 2001 to the Musée des Beaux-Arts in Lyon (statuettes, preparatory studies, plaques, glass plates), and in 1997 to the Musée départemental de l'Oise - Beauvais, where the addition of around forty sculptures and drawings to the collections led to a temporary exhibition entirely dedicated to Louis Castex, between November 1997 and January 1998.
