"Canada might not be known for its castles, but Toronto is home to an unusual one that has become a beloved tourist attraction. Casa Loma is a 98-room château built by Canadian businessman Sir Henry Mill Pellatt in 1914, who went bankrupt shortly after completing his beloved home. Casa Loma now serves as a museum and a popular filming location, most notably serving as Professor Xavier’s School for Gifted Youngers in X-Men. Do the self-guided tour, which you can fly through at a clip, providing the place isn't packed; it can be tricky to rush past the crowds during busier times, especially in some of the smaller spaces, tunnels, and towers. Must-sees include secret passageways, gardens, and an underground pool." - Stefanie Waldek
