The Church of St. John in Aix-en-Provence, situated at the corner of rue d'Italie and rue Cardinale, is a Gothic Roman Catholic church, the first in Provence. It was built in the 13th century, mostly in the 1270s.
The site was initially occupied in the twelfth century by a hospice and chapel of the Knights Hospitaller of the Order of Malta, under the jurisdiction of the priory of Saint-Gilles in Provence. The thirteenth-century church formed part of a priory of the same order situated in olive groves outside the city walls of Aix. From the thirteenth century it served as a burial place for the Counts of Provence.
In the 17th century the parish was incorporated within the city of Aix when the ramparts were extended to the south and the adjoining lands of the priory sold off to help create the quartier Mazarin. In the aftermath of the French revolution most of the internal furnishings, treasures and statuary of the church were removed or plundered and the church itself converted into a military storehouse. In the 19th century it was eventually restored to religious use as a parish church.
The church is currently under the ministry of a brotherhood of apostolic monks. The nineteenth century organ in Saint-Jean-de-Malte was replaced in 2006 by a baroque-style organ built by Daniel Kern. The interior of the church may be seen in Michelangelo Antonioni's 1995 film Beyond the Clouds.
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.
