The cathedral of Marseille is a Roman Catholic basilica minor located in Marseille. It acts as the seat of the Archdioses of Marseille. The present cathedral was built in a Byzantine-Roman style by architects Léon Vaudover and Henri-Jacques Espérandieu with a 70 meters high cupola and a length of 142 meters, making one of the largest in France.
Before the present cathedral existed, there was an older one which was much smaller and some of the remains can still be seen. Built in the 12th century and demolished in the 1850’s, it was built in a very simple romanesque style.
