Mosque of the Bois de Vincennes

The Mosque of the Bois de Vincennes (French: Mosquée du Bois de Vincennes), also known as the Mosque of the Colonial Garden Hospital or Nogent Mosque was a former Islamic mosque, located in the grounds of the Bois de Vincennes, in greater Paris, France. It was the first mosque built on the French mainland since the Umayyad invasion of Gaul in the 8th century and the conversion of the Toulon Cathedral by the Ottomans. The mosque was constructed in early 1916 on the grounds of the Bois de Vincennes, as a counterpropaganda project and to serve some of the Muslim soldiers who came to France during World War I. The mosque was destroyed just four years later, in 1920.
