 Most strikingly, the venues, wrought of glass, pre-stressed concrete and wood, were to be encased in and connected via six giant shell or upside-down-hull copper roof structures from which the French name, "d'Coque" derived.Tallibert's designs were heavily informed by his then ongoing works on the Montreal Olympic Park, for the 1976 Summer Olympics.Similarities in design, materials and architectural style are particularly visible when comparing d'Coque with his work on Montreal's Olympic pool, stadium and velodrome (since refurbished as a biodome).
