Vieille Major, Romanesque church in 2nd arrondissement of Marseille, France

Vieille Major is a Romanesque church in Marseille's 2nd arrondissement featuring a barrel-vaulted ceiling, an octagonal dome above the transept crossing, and a semi-dome covering the heptagonal apse. The structure combines geometric forms with thick stone walls that reflect the age of the building.

The church was built in the 12th century on the remains of a 5th-century place of worship and served as Marseille's cathedral for centuries. Its role ended when a new cathedral was constructed, causing this older building to decline in importance.

The choir stalls and wooden pulpit were bought in 1794 by the Italian shipowner Luigi Oxilia to save them from revolutionaries who wanted to burn them, and moved to the basilica of San Nicolò at Pietra Ligure in Italy. In the Saint-Sérénus chapel a glazed terracotta relief of the Entombment is attributed to Luca della Robbia's workshop.

The building is normally closed to the public but opens for special occasions such as Heritage Days. Visitors should check local event calendars to find opportunities to explore the interior.

The building was nearly demolished in 1852, but the French Society for the Conservation of Monuments and public opposition saved it from destruction. This rescue made it an early example of heritage protection in France.
