Traces of occupation dating from the Gallo-Roman period were found there (vestiges of workshops, a sculpted head, etc.).

Chateau St. Julien l'Ars still stands after extensive renovations done in the 1860s by Robert de Beauchamp.

Saint-Julien-l'Ars welcomed the progress of the French Revolution and planted the Tree of Freedom to symbolize it.

It became the rallying point for all the major festivals and events related to the revolution including the anniversary of the execution of King Louis XVI.

[9] Saint-Julien-l'Ars Station was commissioned on 18 June 1883 by the State, to exploit the Mignaloux-Nouaille-to-Chauvigny section of the Saint-Benoît-to-Blanc rail line.
