The building of Lescar Cathedral was begun in 1120 by Bishop Guy de Lons, and was sacked by the Protestants during the reign of Jeanne III of Navarre. It was restored in the 17th and 18th centuries. The apse, housing a pavement mosaic from the 12th century with hunting scenes, is in Romanesque style. In the interior, columns have capitals depicting histories of the life of Daniel, of the birth of Christ and the Sacrifice of Isaac.
From the end of the 15th century the cathedral was used as the burial place of the royal family of Navarre. Francis Phoebus was buried here in 1483, followed by Catherine of Navarre, her consort Jean d'Albret and several of their children, among them Henry II of Navarreand his wife Marguerite of Angoulême, grandparents of King Henry IV of France.
Of the funerary monuments ordered by Henry II, subjected to iconoclastic damage by Protestants and to the collapse of the sanctuary vault in 1599, nothing remains. Archaeological excavations in 1928-1929 were successful however in rediscovering the royal crypt and the remains of its occupants.
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.
