Susa Cathedral is the seat of the Bishop of Susa and is dedicated to Saint Justus of Novalesa. In origin it was the church of the Benedictine Abbey of St. Justus, established in 1029 by Marchese Olderico Manfredi to house the newly discovered relics of Saint Justus. The church was built around 1100 and has since been refurbished and restored several times. It was not until 1772 that the bishopric of Susa was created from the territory of the abbey, previously a territorial abbacy, and at that point the abbey church was made the cathedral of the new diocese.
The cathedral is a Romanesque style building. The façade has terracotta decorations and is joined to a Roman gate of the 4th century, the Porta Savoia, to the south. Halfway along the south side stands the campanile, with six levels of mullioned windows.
The interior is on the Latin Cross plan, with three aisles. It contains a baptistry which is earlier than the present church, and a statue supposedly of Adelaide, Marchioness of Turin, daughter and heiress of Olderico Manfredi and wife of Otto, Count of Savoy, ancestress of the Royal House of Savoy.
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.
