The House of Occitanie tells a story and heritage through its walls. For this reason, several exhibition or meeting rooms are named after figures from Occitan history.

Antonin Perbosc (1861-1944) was an ethnographer and Occitan poet. Straddling lyrical and narrative poetry, he authored about ten works, such as Lo Got occitan or Libre dels Auzèls. He was very active in the Félibres movement and participated in founding the Escôla Occitana in 1919, aimed at revitalizing Occitan. He was elected majoral of Félibrige in 1892.

René Nelli (1906-1982) was an Occitan poet, philosopher, and historian of Catharism. He dedicated much of his work to studying and promoting Occitan culture and Cathar dualism. The author played an important role in enhancing knowledge of Occitan culture, notably by participating in the founding of the Institute of Occitan Studies in 1945. He wrote, among other works, Entre l’esper e l’abséncia, Spiritulité du catharisme, and Aram de Vertat.
