Built between 1878 and 1881, the fort is part of the Séré de Rivières system of fortifications built in the late 19th century. It has been rehabilitated as a contemporary artists' community. The ''Fort en Jazz'' festival is held there each year.〔http://www.mairie-francheville69.fr/vc_page38.php page de la mairie sur le fort〕 == Concept and design == The Fort de Bruissin is located about to the southeast of the center of Lyon. Lyon's original protective ring of forts was built in the 1830s at a distance from the city just beyond the range of the artillery of the era, thus denying a potential attacker the means to bombard Lyon. With the introduction of rifled artillery, the range increased, placing the city once again into jeopardy. In the 1870s a second ring of forts was built father out to deal with the extended range of artillery. Work on the second ring of eighteen forts was complete by 1893. The Fort du Bruissin was number 13 in the Army's numerical designation of the forts of Lyon. The Fort de Bruissin is a six-sided polygon, with masonry walls surrounded by a defended ditch. The most striking feature of the fort is its entry court, reached through a gatehouse at the head of a bridge over the ditch. A two-level vaulted barracks faces the gatehouse across the court, covered with earth. A terrace or cavalier on top of the barracks was shielded by an earth rampart. The fort was primarily armed with a mixture of 155mm and 120mm guns. located on the cavalier within the walls of the fort. Close-in defense was provided by revolving cannons in large caponiers at the corners of the fort, reached by subterranean passages.〔 The fort was initially manned by 294 men, serving a total of thirty artillery pieces.
