Engineer and geologist Martin Anctil excavates the Sillery sandstone, which has been used in many of the city's centuries-old buildings, in his Lévis quarry. "The spirit of that type of restoration has always been very clear: it is to use the construction's original stone when it is available." Martin Anctil owns a quarry which excavates Sillery sandstone in Lévis, across the St. Lawrence River from Quebec City. Pennsylvania Bluestone, left, is being used to restore a section of the historic Citadelle fortress in Quebec City, but the original material, Sillery sandstone, is readily available nearby. The three other masonry companies that proposed to use the original stone told Radio-Canada they would never have suggested using another material than the Sillery sandstone.
