Casa Rome is a must-have for Chinese tourists in Toronto. The entire castle, which covers 5 acres, is the only complete-scale castle in North America, a 200,000-square-foot Edwardian-style castle that employs 300 workers and took nearly three years to build at a cost of $3.5 million. It was Sir Henry Parrett's 1911 appointment of the famous architect E. J. Linus to achieve his lifelong dream of becoming the most luxurious and largest private mansion in Canada.
