Canadian Tulip Festival in Ottawa
Ottawa's Commissioners Park and the shoreline of Dow's Lake fill with more than a million tulips each May, the living legacy of a wartime gift from the Dutch royal family after Princess Juliana sheltered in Canada during the Nazi occupation of the Netherlands. Started as a public festival in 1953 by photojournalist Malak Karsh, it now runs eleven days with a self-guided Tulip Trail linking the main flower displays around the city.
Ottawa's tulip festival traces back to a specific wartime debt: when Nazi Germany occupied the Netherlands, Crown Princess Juliana and her daughters took refuge in Ottawa, and in 1943 she gave birth to Princess Margriet at the Civic Hospital, in a delivery room the Canadian government briefly declared extraterritorial so the newborn princess would hold Dutch nationality alone, keeping her place in the line of succession intact.
