For the bi-centenary commemoration of the French Revolution, the Viry firm built two pavilions whose exceptional design gave unobstructed visibility of the festivities held in the Tuileries gardens. With their slender metal frames, the towers formed two belvederes complete with reception and exhibition lounges facing the Seine: visitors were on a level with the tree tops in the park. Textile screens extended from the edifice to form large aerial corollas. Although designed for an ephemeral event, the towers used advanced technologies to ensure perfect security for users. Dismantled after the celebrations, one of them was re-erected in the town of Saint-Die.
