In Quebec, the benchmark for architectural stone is inarguably St-Marc limestone. Used as building stone since around 1835, its reputation is firmly established. It has been used for many important Québec City buildings such as the Palais Montcalm, the Citadelle, city hall, the Parliament building and, of course, the Château Frontenac. Limestone offers versatility and durability combined with a striking look. It's a nobel choice for major construction work here and abroad.
