The 1993 addition to the Chateau Frontenac Hotel in Quebec City.

The architects who designed the new wing copied the style of the original hotel. The Historic District of Old Quebec was designated a UNESCO World Heritage Site partly to preserve and protect the following landmarks:
The Chateau Frontenac
Place Royale and Petit-Champlain
Old Port - the ESpace 400e Pavilion is currently for sale by the federal government.
Rue Saint-Jean
Parliament Hill
The Plains of Abraham
The Fortifications of Quebec.
A few years ago I visited Quebec City and many of the churches are facing an uncertain future. Our tour bus operator pointed out the different locales where Celine Dion performed including churches, a concert hall and the Plains of Abraham.
The following sites were also memorable, to me:
1.)  The terrace at the Chateau Frontenac where dancers and musicians performed.
2,)   The cobblestone streets.
3.)  The many statues.
4.)   Louis S. St-Laurent Building at 3 Passage du chien d'or where I mailed postcards.
5.)   Gare du Palais where the Via train station and a bus depot are located.
6.)   An elevator between upper and lower town called the Funicular Lift.
7.)  The lobby at the Chateau where a dog (a Labrador Retriever I believe) is a permanent resident.
