Casa Loma is a gothic manison built by Sir Henry Mill Pellatt. It is located midtown Toronto. The design is by E J Lennox and took three years to built. Due to the outbreak of World War I, the construction halted in 1914, but most of the manor was already completed. It has 98 rooms and is the largest private residence ever built in Canada. Today the house is open to the public, serving as a museum. The manor has stables, five gardens, a basement and three floors. On the third floor is The Queen's Own Rifles of Canada Regimental Museum. The house is operated by the Kiwanis Club of Toronto.
