Église Saint-Vincent-de-Paul was built on a demolished convent and chapel of Reformed Augustinians, which explains why it is commonly known as 'Les Réformés' despite being a Roman Catholic church. The church building itself was designed by the architect François Reybaud and the abbey Joseph-Guillaume Pougnet, and built from 1855 to 1886. It is neogothic, with ogival curbs in the ceiling. The two arrows are 70 metre high.
The bronze gates were designed by Caras-Latour, the high altar was designed by Jules Cantini (1826-1916), and the stained windows were designed by Édouard Didron (1836-1902). Additionally, sculptor Louis Botinelly (1883-1962) designed the statues of Joan of Arc and of Jesus. As for the organ pipes, they were made by Joseph Merklin (1819–1905).
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.
