La Citadelle in Arras, Francewas built in the 17th century, this pentagonal fortress features a WWII memorial, recreation centre & a chapel.

The construction of the citadel is planned in five different locations in Arras: in the city, near the main square, at the Ronville gate, in the Baudimont structure or between the Amiens and Hagerue gates. It is this last location which is chosen because it forms a right angle between the town and the city. Construction began in 1668 and ended in 16701. At the same time, the ramparts suffered.

When Vauban defined his area intended to ensure French defense against invasions, he defined a second line of defense at Arras, and had the city’s citadel built. Never attacked, this citadel is nicknamed “the beautiful useless one”. According to Charles de Lalleau, the nickname comes from the fact that there was no easement between Arras and its citadel. The ramparts were destroyed late and the esplanade was not formed4.

In 1715, certain underground passages were used as prisons.

In 1830, after the constitutional charter of August 14, the citadel temple was transformed into a store. It has been falling into disrepair since.
