Converted to a cathedral in 1536 when the Archdiocese of Maguelone was transferred to Montpellier, it was originally the chapel belonging to the Benedictine monastery.
Absolutely not to be missed: the porch, an imposing canopy supported by enormous circular pillars measuring 4.55 metres in diameter, that once bore the arms of Urban V, a former student and teacher in Montpellier, later appointed bishop before being elected pope in Avignon (1362).
It is a representative example of the Gothic style in the South of France and the only medieval church in the Ecusson to have survived the Wars of Religion.
Inside, a major piece by Sébastien Bourdon, The Fall of Simon Magus, will sweep you away into the artistic life of 17th century Montpellier. The painting depicts an apocryphal episode from the life of Saint Peter (whose name the cathedral also bears).
Montpellier Cathedral has been a listed Historical Monument since 1906.
