The Chapelle de la Trinité is the first church in baroque style built in Lyon. It was created by the architect Étienne Martellange, a Jesuit brother who introduced architectural models of the Counter-Reformation in Lyon. Built between 1617 and 1622, the chapel is located within the building of the Grand Collège, under the direction of the Jesuits since 1567. It was devoted to college students. It was consecrated in 1622. The decor is very refined with coatings of Carrara marble.
Until September 1799, the chapel served as a barracks. In 1801, the First Consul was there proclaimed President of the Italian Republic. Thomas Blanchet, Horace le Blanc, Magnan and Pierre David are the sculptors or painters whose works can be seen in the chapel. There are often patrimonial visits, haute couture shows, seminars and charity work in the chapel. About 30,000 people visit it each year.
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.
