Basilica di Santo Stefano Maggiore was established in the 5th century. Originally dedicated to both Saint Zechariah and Saint Stephen, it was later dedicated to Saint Stephen only. Throughout its history, has undergone several reconstructions, expansion and restoration.
The original church building was built around the year 417 on the initiative of the future bishop Martinianus. It was destroyed by fire in 1070 and it was rebuilt in romanesque style in 1075.
On 26 December 1476 it was the site of the assassination of Duke Galeazzo Maria Sforza, who had come to the basilica for the celebration of the patron saint. On 30 September 1571 in Santo Stefano was baptized the painter Michelangelo Merisi, better known as Caravaggio.
Since 1594 the church underwent a series of interventions, including enlargement of the apse and of the main altar in the early 17th century.
The church preserved the bodies of saints Martinianus, Ausanus and Mansuetus, archbishops of Milan, in 1988 translated to the Milan Cathedral. St. Charles Borromeo also translated here the bodies of saints Leo, Arsazius, Marinus, Mammes and Agapetus.
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.
