Curepipe
These barracks had tall stone walls and featured metal "S" shapes, which were put up by the French military engineers at the time. Curepipe really started to grow when a malaria outbreak hit in the 1860s. Many folks from Port Louis moved to the cooler highlands to escape the disease.
The town also saw early development with roads, shops, and housing popping up. They both share a road named after Docteur Joseph Rivière.
Port Louis
The Casernes Centrales, or Line Barracks, were built between 1740 and 1744 under French Governor Bertrand-François Mahé de Labourdonnais. In 1922, the barracks were turned into the colony’s police headquarters, which is still in use today.
The "Caserne" in Port Louis, known as Caserne Centrale, refers to these historical barracks from the French colonial era. The word "caserne" itself comes from the French term for barracks, originally meant to house French and later British troops. The complex initially served as the headquarters for colonial forces from both nations.
