2. Vienne Cathedral
A French National Monument, Vienne Cathedral is not strictly a cathedral as the archdiocese of Vienne was abolished at the start of the 1800s.
What you see today is mostly romanesque and gothic from between the 12th and 14th centuries, but with some later additions after the building was damaged by the Huguenots in the French Wars of Religion.
The western facade, facing the Rhône, is a treasure and the three expertly-carved portal arches managed to survive the damage.
The right portal shows prophets and angels, the left one is dedicated to the Virgin, while the centre has images you may recognise from the Old and New Testaments.
