In the château style, Château Frontenac is an imposing hotel with five brick and stone wings and a central tower erected in seven stages between 1892 and 1993. It is prominently located on a cliff overlooking the St. Lawrence River, within the Québec historic district. The designation refers to the building on its footprint in 1981 (the date of designation). The Château Frontenac was designated a national historic site because it is an excellent example of a Chateau-style hotel.
