The Church of Notre-Dame in Versailles was built at the command of Louis XIV by Jules Hardouin-Mansart in the Neo-Classical style and was consecrated on 30 October 1686. The parish of Notre-Dame included the Palace of Versailles and thus registered the baptisms, marriages and burials of the French royal family.
In 1791 it was declared a cathedral but converted to a Temple of Reason in 1793. After the Revolution the bishop of Versailles chose the Church of Saint-Louis as his seat instead (the present Versailles Cathedral).
Between 1858 and 1873, a new chapel was added by the architect Le Poittevin, who also built the market-halls of the Marché Notre-Dame.
The church contains sculptures by Pierre Mazzeline and Noël Jouvenet.
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.
