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 Odeon of Herodes Atticus is a stone theatre structure located on the southwest slope of the Acropolis of Athens. It was built in 161 AD by the Athenian magnate Herodes Atticus in memory of his wife, Aspasia Annia Regilla. It was originally a steep-sloped theater with a three-story stone front wall and a wooden roof made of expensive cedar of Lebanon timber. It was used as a venue for music concerts with a capacity of 5,000. It lasted intact until it was destroyed and left in ruins by the Heruli in 267 AD.
The audience stands and the orchestra (stage) were restored using Pentelic marble in the 1950s. Since then it has been the main venue of the Athens Festival, which runs from May through October each year, featuring a variety of acclaimed Greek as well as International performances.
