The Église Saint-Polycarpe (Church of St. Polycarp) is the oldest church of the Oratory of Saint Philip Neri. The church, built by the Oratorians installed on the slopes, was completed in 1670, with the exception of the façade that was built in 1756 by architect Toussaint Loyer who also lengthened the nave.
On 19 June 1791, the Oratory Church became a parish church and took the name of St. Polycarp, as a tribute to Polycarp of Smyrna, master of Saint Pothinus and Irenaeus, who were the first two bishops of Lyon. The church has a famous organ, built by Augustine Zeiger in 1841.
The church has a facade decorated with four Corinthian pilasters topped by a triangular pediment. Louis Janmot made the painting depicting the Last Supper which is placed in the apse.
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.
