Completed in 1863, Sir Hugh Allan's new house, "Ravenscrag", was to be the jewel of the Square Mile, as he intended. He purchased fourteen acres from the decaying McTavish estate and built a sumptuous home of 72 rooms that excelled "in size and cost any dwelling-house in Canada," surpassing Dundurn Castle. By the 1860s, Montreal had come of age, which was recognised by three Royal visits from the future Edward VII, Prince Alfred and Prince Arthur, the most of any colony.
