I was in awe when I visited this Basilica of Saint-Sernin in Toulouse, France which is under UNESCO World Heritage Sites. The architecture was more of a Romanesque of the 4th century. It housed the body of Saint Saturnin or Sernin, who is the first bishop of Toulouse. At that time I was visiting, they were doing restoration on the rear of the Basilica. It was indeed an amazing visit..
