The Basilique de St-Martin in Tours is a neo-Byzantine basilica on the site of previous churches built in honor of St. Martin, bishop of Tours in the 4th century. Next to it are two Romanesque towers and a Renaissance cloister surviving from the earlier basilica.
St. Martin died in 397 at the age of about 81 in Candes, and his body was brought to Tours. Martin's remains were enclosed in a stone sarcophagus, above which his successors, St. Britius and St. Perpetuus, built first a simple chapel, and later a basilica (466-72). St. Euphronius, Bishop of Autun and a friend of St. Perpetuus, sent a sculptured tablet of marble to cover the tomb. This Early Christian basilica burned down along with many other churches in 988.
A larger Basilica of St. Martin was constructed in 1014, which burned down in 1230. This was rebuilt as an even larger 13th-century Romanesque basilica, which became the center of great national pilgrimages and a stop on the way toSantiago. Martin's cult was very popular throughout the Middle Ages and a multitude of churches and chapels have been dedicated to him.
In 1562, Huguenots (French Calvinists) sacked the Basilica of St. Martin from top to bottom, especially destroying the tomb and relics of Martin. The church was restored by its canons, but then was completely demolished in 1793 during the Revolution. All the remained of the basilica was the two towers which are still standing. To ensure the basilica could not be rebuilt, the atheistic municipality caused two streets to be opened up on its site.
In December 1860, excavations located the site of St. Martin's tomb, of which some fragments were discovered. A new basilica to house these relics was constructed by Mgr Meignan, Archbishop of Tours, from 1886-1924. Martin's tomb is still a place of pilgrimage for the faithful.
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.
