It is considered to have the best agricultural land of the entire Abitibi region.

The completion of the National Transcontinental Railway at La Sarre and Macamic led to further waves of development with the arrival of new settlers in 1916, 1918, and 1929.

Following the pattern of other places in the Abitibi, the settlement was named after a historic military figure, François-Charles Bertrand de Palmarole or Palmarolle (1714 ‑ 1760), lieutenant of the La Sarre Regiment and Knight of the Order of Saint Louis.

In 1921, the parish was formed and in 1930, the place was incorporated as a municipality.
