These barracks, which were built with some of the money allocated by Louis XV to reconstruct Pontarlier after the fire in 1736, could house up to 200 men and just as many horses. The two L-shaped buildings were linked by a huge door, however, the municipality refused to close the square on the other side. This place was therefore split between a place of armament and a public place. In 1922, the door was removed, to allow for better circulation. (PNRHJ - Un tour en ville, “A tour of the town”)
