The 'Basilique Saint Sernin de Toulouse' is most famous, vastest and most beautiful of the Romance churches of the South, richest of France in relics. The 'Basilique Saint Sernin de Toulouse' finds her origin in the wish to honour the memory of Saturin, first bishop and martyr of Toulouse.
During the IV. Century, the Hilaire bishop made erect above the place of the casket a small wood basilica to honour the memory of his predecessor. Because of the importance of the devotion and the development of the necropolis caused by the glory and the virtues of the martyr, the Silve bishop undertook towards the end of the IV. Century the construction of a new basilica‐martyrium.
The 'Basilique Saint‐Sernin de Toulouse' has become a major stage on the road of the pilgrimage of Saint‐Jacques de Compostelle and the old church is not enough any more to accomodate crowd which presented itself.
