Of Byzantine inspiration, the Sainte-Marie-Majeure cathedral of Marseille juxtaposes Romanesque and Gothic elements. Structured as a tripartite building composed of a monumental portico framed by two towers, an imposing nave, and a massif grouping the sanctuaries, it forms a remarkable architectural ensemble unparalleled in the entire 19th century. The simultaneous presence of bell towers, domes, and cupolas reminiscent of Istanbul's churches makes West and East coexist on the model of Notre-Dame des Doms in Avignon.
