Embrun Cathedral was the seat of the former Archbishopric of Embrun, which was divided between the Bishopric of Gap and the Archbishopric of Aix in 1822. On its door were posted in 1489 the thirty-two propositions imputed to the Waldenses, that presaged the campaign to extirpate them as heretics, which resurfaced in the Dauphiné with intense savagery during the Wars of Religion in France: Lesdiguières pillaged Embrun Cathedral in 1585. This saw the destruction of a fresco, probably painted in the 13th century, representing the Madonna, which had been the object of a celebrated pilgrimage for many centuries.
In the fifth century relics of St Nazarius were translated to Embrun, which had supported a bishop since the fourth century; Embrun became a noted place of pilgrimage. Charlemagne erected the basilica that was visited by Pope Leo III.
The cathedral church, built on foundations that date to its founding in the ninth century, was constructed between 1170 and 1220; its Romanesque portal, columns supported on crouching lions in the north portal and striped stonework courses in cream and gray stone express cultural links with Lombardy. The interior has an elaborate Baroque high altar inlaid in colored marbles, recently rediscovered frescoes, an organ (the oldest working in France) donated by Louis XI of France.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
