In 1775, the intendant of Brittany Caze de la Bôve redeveloped an old square planted promenade embellished with a fountain. It stretches from the church of Saint-Louis (now disappeared and materialized by the residence Plein Ciel) to the quai des Indes. These developments are contemporary with the appearance of a new population in Lorient: the trading bourgeoisie. The construction of an Italian theatre at the bottom of the course marks the height of their influence on public life. The building, built in the late 19th century in block stone at the corner of the Cours de la Bôve and the rue du port, has all the characteristics of the Haussmann style implemented in Paris in the years 1850-1860 and three levels of decreasing height.
