Some of Canada's most unique features are the majestic hotels that were built across the country from the late 1800s well into the 20th Century. The two main railways, the Canadian Pacific and the Canadian National (and its predecessors) built many of these. For their time they were miracles of construction and engineering, and attracted worldwide attention and admiration. They have become something that is associated with Canada and are a part of the national heritage and identity. Hotels of similar design were built in other places, and many of these are also among the world's 'Grand Hotels.'
