Between 1828 and 1848, Barthélemy built several infrastructures: saw and carding mills on the banks of the L’Assomption River, a public market, a church, a presbytery and a college.
He also built a railroad linking the sawmills to the Lanoraie dock.
Finally, he was also behind the construction of an imposing stone manor house and other mills on the site of today’s Les Mélèzes school.
In 1847, the Clercs de Saint-Viateur came to the village to provide education for the boys at Collège Joliette. Their impact on Joliette’s cultural life is significant, and still remains today.
In 1863, the Village de l’Industrie changed its name to Joliette, in honour of its founder.
